Response to Paul Collier: Chapter 2

(This post is part of a series in response to Paul Collier’s Exodus. See my response to Chapter 1.)

Chapter 2 of the migration-skeptical economist Paul Collier’s Exodus is entitled “Why Migration Accelerates,” but he starts by explaining the wealth and poverty of nations. The way he does so sets the stage for serious doubts about the beneficence of migration. He summarizes the state of development economics as follows:

When development economics was in its infancy, the standard explanation for the astounding gap in income was the difference in the endowment of capital. Workers in high-income countries were more productive because they had so much more capital with which to work… [But] capital… can no longer be seen as the primary cause of… poverty; something else must jointly account for their lack of capital and their poverty. Poor choices in economic policy, dysfunctional ideologies, bad geography, negative attitudes about work, the legacy of colonialism, and a lack of education have all been proposed and investigated as explanations…

Increasingly, economists and political scientists have coalesced around explanations that focus on how the polity is organized: how political interest groups shape long-lasting institutions that thereafter affect choices. One influential line of argument is that the key initial conditions for prosperity are those in which it is in the interest of political elites to build a tax system: historically in Europe they needed revenues to finance military spending. In turn, a tax system gives a government an interest in enlarging the economy, and so induces it to build the rule of law…

A related line of argument is that the key institutional change is the shift in political power from predatory elites bent on extracting revenues from the productive population to more inclusive institutions that protect the interests of the productive. In an important new study, Daron Acemoglu and James Robinson argue that the English Glorious Revolution of 1688, in which power shifted from king to Parliament, was the first such decisive event in world economic history, unleashing the Industrial Revolution and opening the path to global prosperity.

Alas, this may be an accurate summary of the state of development economics, but it makes me want to cry. The study to which Collier refers, Why Nations Fail, is one of the most over-rated books I’ve ever read. It’s fatally unrigorous, equally destitute of formal theory and econometrics. A naïve view of the beneficence of democracy has long since been ripped apart by public choice economics, yet Acemoglu and Robinson revive it in the crudest form. People good, elites bad. The book is somewhat persuasive via selective anecdotes if you’re willing to swallow its bizarre terminology, e.g., “inclusive economic institutions” means protection of property rights, even though property rights consist precisely in the right to exclude others. All in all, I tend to think development economics peaked with the empirical work of Jeffery Sachs in the 1990s, and it’s been downhill from there. Daron Acemoglu, in particular, has been a disaster for the field. Honest empirical work on the democracy => growth causal link suggests that the effect is basically nil. But Acemoglu and Robinson’s tendentiously fact-packed and conceptually confusing tome has given development economists a pretext for taking a more politically correct view.

In spite of my dismay at his embrace of Acemoglu, I wouldn’t wholly deny Collier’s claim that national wealth depends on institutions and on a country’s social model, and he is certainly right that “democratic political institutions only function well if ordinary citizens are sufficiently well informed to discipline politicians.” In fact, it’s a bit of a mystery why democracy works even in the mediocre fashion that it does work, in view of rational voter ignorance, Arrow’s impossibility theorem, and other public choice insights, and I think the explanation of the mystery has a lot to do with overlapping webs of altruism among fellow nationals. That’s why ethnic fragmentation in a democracy can lead to disaster: each side cares only about its own, and elections become a contest to grab the spoils of office. But never forget this: open borders does not mean open citizenship. It’s fine to let people come and not let them vote.

Collier writes that “many of the rules that govern economic behavior are informal, so the analysis [of the determinants of wealth] can be extended beyond institutions and narratives to social norms.” Yes, social norms can facilitate economic cooperation. Yes, immigrants may not share the social norms that enable natives to cooperate. But it does not follow that immigrants will undermine economic cooperation among natives. After all, if immigrants don’t share certain social norms that make certain kinds of economic cooperation among natives possible, natives can simply go on cooperating among themselves in the ways that require those norms, and not with natives. Does that sound like reprehensible discrimination? If so, I’m OK with that, but I don’t really think discrimination is involved here.

Here is the key question: How frequent, and how important, are trust-based transactions with total strangers randomly selected from the resident population? If the answers are “frequently” and “very important,” then Collier has good reason to worry about immigration. If much of our prosperity depends on our being able to bump into random people on the street and do big deals with them that aren’t adequately covered by contracts but involve major reliance on shared social norms, cultural understanding, and character-based trust, then letting the native population be greatly diluted by a large influx of foreigners from countries with dysfunctional social models really might impoverish us.

But I think the answers are “pretty infrequent” and “not very important at all.” Continue reading Response to Paul Collier: Chapter 2

Open borders and liberal interventionism

The Syria crisis was an expose of US war-weariness, weakness of will, and indecision, as Timothy Garton Ash, among many others, recently observed. The contrast between the US in 2003, when a large majority of the American public favored the liberation of Iraq, and the US in 2013, when…

Every one of the countless members of Congress I’ve seen interviewed on cable television news has acknowledged this, be they Republican or Democrat, for or against striking Syria. Only “three or four” of at least a thousand constituents he’s talked to favour military action, reports Congressman Elijah Cummings, a Democrat and Obama supporter. Senator Rand (son of Ron) Paul, a rising star of the Republican party, says his phone calls are “100 to 1” against war.

… is remarkable, particularly considering that the administration’s proposed action in Syria, though vague, appeared to be much more limited, and motivated as an immediate reaction to a chemical-weapons atrocity. Of course, one can’t necessarily read the difference in public opinion as a barometer of where Americans stand on the “isolationism” vs. interventionism spectrum. I supported the Iraq war in 2003, though I foresaw it would lead to a bloody mess, because even anarchy is better than totalitarianism, and I have never repented of it. The closest I came to regretting it was in 2006, but I wasn’t that close, and after the success of the “surge” I became stronger in my retrospective agreement with myself. But I was skeptical of Syria intervention because the administration didn’t seem to have a plan that made strategic sense, let alone a will to follow through with it. Still, for the moment it looks like the eclipse of liberal interventionism:

Last but not least, there are still a few liberal, humanitarian interventionists, of the old 1990s genre, shaped by the experiences of Bosnia, Rwanda and Kosovo. Obama has appointed as his ambassador to the UN an almost totemic representative of that persuasion, Samantha Power, the author of a 2002 book called A Problem from Hell: America and the Age of Genocide. Well, Syria is a problem from hell, all right. These liberal humanitarian interventionists are not the predominant voice in an administration characterised by cautious, security-first pragmatism, but they’re still there.

Ash suggests that this episode of US “isolationism” (my libertarian-pacifist friends would object that it’s not really isolationism because it’s consistent with support for free trade, hence the scare quotes) may be more lasting than previous episodes:

“Isolationism” is the lazy term often applied to the attitude now found among Democrats and Republicans alike. It is true that the US has a history of periodically withdrawing into its own vast continental indifference, as it did after the first world war. But this time feels different. While the current withdrawalism undoubtedly drinks from some of those traditional wells, it flows through a country not brashly rising on the world stage but fearfully conscious of relative decline. Back in the 1920s, Americans were not worried about a rising China eating their lunch – and then buying the hamburger stall. They are now.

Maybe, though in the relatively “isolationist” 1970s we were worried about relative economic decline, too. Still, it’s plausible. The US share of the global economy has been in decline ever since World War II, but especially in the past decade, and there must be some limit to how far the US can decline in relative economic power while still playing a leadership role in the world. The subtitle of Ash’s article is “The nation is sick and tired of foreign wars, and may never play its role of global anchor again. We may live to regret it.” Ash is British, and not everyone would regard US leadership in the world as benign. But many would.

Now, here’s what must always be remembered in such discussions. Relative US economic decline, and the decline in military pre-eminence and global influence that is linked to it, is a choice. The US could easily restore its economic weight in the world by opening its borders to tens or hundreds of millions of immigrants. They want to come. Many are more or less pre-assimilated, English-speaking and familiar with American culture and liberal democracy. By letting them in, the US could have burgeoning cities, growing GDP, rising tax revenue, and more military recruits. The US could also diversify its array of global contacts still further, and exert remote influence via return migration and letters home. If the intelligence services were at all enterprising they could find useful information among resident expatriates from around the world. And accepting immigrants would, by itself, win goodwill around the world. That would put the US in a better position, in future, to stop tyrants like Assad.

If we’re still worried about the freedom and safety of Syrians, open borders could accomplish a lot of that directly, simply by giving Syrians somewhere to go. For the more adventurously inclined, open borders could contribute to freedom in Syria and elsewhere in another way. Before and during the liberation of Iraq in 2003, many anti-war types dodged being called pro-Saddam by saying that they were all in favor of Saddam being overthrown, but they wanted it to be done by Iraqis. I think I recall at least one libertarian adding that he’d be OK with a private war of libertarian against Saddam– think of idealistic volunteers forming a private army to overthrow the tyrant– but that he had a problem with the US government doing it, because the US government has a mandate only to protect US citizens, and even if liberation does benefit Iraqis, it is not entitled to use Americans’ tax dollars that way. Under open borders, Syrian rebels could come to the US and tour the country asking for donations to rid themselves of the tyrant.

Liberal interventionists are willing to sacrifice their own resources for the lives and liberties of foreigners. Good for them. But they really ought, then, to favor open borders, which will allow foreigners to save their own lives and liberties, whether merely by escaping, or perhaps by seeking support for their causes abroad, not through governments, but through the voluntary generosity of well-wishers of liberty.

Response to Paul Collier: Chapter 1

Paul Collier’s Exodus: How Migration is Changing Our World is probably the best book on migration from the restrictionist side that currently exists. Though, that is not saying much. It is pretty strong on the economics, and while I find Collier’s ethical attitudes weird, repugnant, and indefensible, they serve as a useful window on the way a lot of people think. Exodus is a refreshing contrast to books like Victor Davis Hanson’s Mexifornia: A State of Becoming. The arguments in Hanson’s book are too thoroughly flawed to be answered. You’d have to rip them to shreds, almost sentence by sentence, to avoid leaving the impression that anything in them is valid. Any reader who would be a worthy interlocutor in a learned conversation would have seen through books like these. My advice to writers like Hanson is to read Collier’s book and spend a couple of weeks contemplating its intellectual merits, and then ask themselves seriously whether they can emulate them sufficiently that their future writings will be net positive contributions to public debate. If Collier sets the standard that future restrictionist writings will be expected to live up to, the quality of public discourse about immigration will be vastly improved.

Interestingly, Exodus is responding in part to open borders as a political cause, even if it’s a cause that his implicit interlocutors don’t usually embrace explicitly. Whereas others will speak loosely of “the open borders lobby” as an epithet to characterize mainstream people who, in fact, want a lot of immigration restriction, Collier is a development economist who has some idea what real open borders would mean, and knows that there is a case for it. He seems to know about the double world GDP literature. So far, the debate has been conducted within the restrictionist end of the spectrum, with advocates of more migration sometimes mistaking themselves for open borders advocates because they’re naïve about how radical open borders really is. Collier thinks about migration in the context of the global struggle against poverty. He doesn’t pretend the rest of the world isn’t there. He doesn’t adopt a principle of moral indifference to the rest of mankind. That’s a big improvement over previous restrictionist literature.

At present, then, Exodus is the argument to beat on the question of open borders. For that reason, I thought it deserved, not just a book review, but a thoroughgoing engagement with the argument. That said, Collier gave me very little reason to change my mind about supporting open borders, though he might have convinced me to shift my position on a few aspects of the question in subtle ways. There are two main reasons that Collier is unconvincing. First, he has the wrong ethics: he knows about “utilitarian universalism” but is constantly engaged in inadequately motivated attempts to substitute manifestly inferior ethical ideas. Second, his policy imagination is very deficient. My greatest regret is that Collier doesn’t engage with DRITI. Again and again, I found myself saying, “Yes, that’s a problem, but DRITI solves it.”

Chapter 1 sets the stage for Collier’s book with a lot of reflections on the peculiar character of the public debate about immigration. For example, he writes that… Continue reading Response to Paul Collier: Chapter 1

Private discrimination against immigrants is morally fine, and should be legal

I’ve been reading Paul Collier’s Exodus, and plan to write a series of posts in response to it soon. Meanwhile, I might as well lay the groundwork for that by jotting down a few reflections.

Here’s one. I’ve commented before on Robert Putnam’s research about immigration and social capital, or really, about ethnic diversity and social capital. He finds that in ethnically mixed settings people tend to “hunker down,” become less sociable, not only with other ethnic groups, but even among themselves. Putnam suggests, and Collier expands on the idea, that immigration could harm social capital. See our page on social capital decline. Also related are the writings of Hans-Herman Hoppe on immigration as “forced integration,” which I have previously responded to here. Thomas E. Woods recently wrote in this vein at The Freeman. Woods’ article, which contains phrases like “immigrants and the American bureaucracy that serves them” (!), is basically silly, but it does contain some serious ideas. In particular, Hoppe and Putnam have a point about “forced integration,” though it’s not the one they think they have.

Hoppe’s starting point is a “pure private property” society in which even streets are privately owned. This is completely unworkable, since it would create endless hold-up problems, and also unjust, since there is no just way for this kind of property regime to originate. As my theory of streets Principles of a Free Society elucidates, natural easements arise from people’s need to move onto and off of their property, and where these easements coincide to form streets, there is a place where over-lapping non-exclusive transit rights prevent individual appropriation. Consequently, no one can be excluded, including immigrants. There is some scope here for gated communities and other explicit contractual arrangements to “privatize,” as it were, streets that serve functions that go beyond mere transit. If a road also serves as a place for your club to meet and socialize, and no one outside the club has any claims on it, you might be justified in restricting access to it. That leaves some space in which Hoppian local communes, so to speak, might be carved out. But to say that immigration should be left to local communities to decide and then use that as a platform from which to demand harsh national immigration restrictions is absurd. Local communities are not, in general, well-defined. There would rarely be local agreement on whom to let in. Enforcement would be an insuperable problem. Some communities would choose to be largely open to the world, and would expand. The Hoppe plan would basically break down, resulting in some combination of open borders and local squabbling lead to the arbitrary denial to many individuals of the full and proper use of their own property. It is completely untenable to regard the mere entry of foreigners into the country, without the state using force to stop them, as “forced integration” by the state. Nativists are lying to themselves if they think is open borders advocates, rather than themselves, who are using force.

But if the government not only permits the entry of immigrants, but also requires native citizens to interact with them on equal terms, on pain of falling foul of anti-discrimination laws, then a complaint of “forced integration” has merit. More generally, all manner of state-mandated equal opportunity and anti-discrimination rules amount to “forced integration.” That’s not to say we shouldn’t have them. Here my attitude is ambivalent. On the one hand, anti-discrimination law is an extremely sinister extension of the state’s jurisdiction. If a classic liberal state only enforces contracts, an anti-discrimination state micromanages what contracts you can sign, and, worst of all, does so on very subjective and non-transparent grounds. On the other hand, the evil which anti-discrimination law in the US was instituted to deal with– the vast historic crime of slavery, and its legacy of segregation– was very great. I am inclined to feel that the state’s act in prohibiting private discrimination was an intolerable affront to the rights of private contract, and at the same time, that it might have been worth it.

Of course, we don’t know what would have happened if the state had simply abolished de jure discrimination on the part of the government, and left private discrimination to individual conscience and civil society. There has been a revolution in values over the past generation to the point where I highly doubt that much private racial discrimination would occur, even if it were absolutely legal. Perhaps the achievements of the civil rights movement could have been accomplished without the sinister extension of state power to micromanage private decision-making. Indeed, perhaps it would have been even more successful. After all, there is a sense in which affirmative action makes racism true. If a university deliberately seeks to hire a diverse faculty, it will face trade-offs between racial/diversity criteria, which favor minorities, and other criteria. Ceteris paribus, that will mean that minority faculty will be lower in quality in other respects. If that’s the hiring process, it will be quite rational for faculty to think, even if they wouldn’t dare say, “He’s black, so he’s probably not that smart.” That may not be a valid statement globally, but it will be valid locally, precisely because affirmative action engineers things to be that way. Of course, affirmative action violates the norm of color-blindness, and it would be difficult to imagine in what sense it could fail to be regarded as unfair. It may lead to resentment, but even if not, people are rational, and if conditions have been created such that there is a local negative correlation between minority status and intelligence, experience, conscientiousness, or whatever, then their beliefs will reflect that.

Discrimination is regarded nowadays as almost the one unforgivable sin. One is indoctrinated against it in school, as one is not indoctrinated against fornication, adultery, or even theft. This is very misguided. It’s highly questionable whether discrimination, in general, is even wrong. Consider the following three motives for discrimination:

1. Hatred of the other. You don’t hire, don’t want to work with, don’t want to be served by, don’t want to rent a room to, don’t want to sell to, etc., members of a minority group, because you hate them. You regard them as inferior and/or bad, and find interaction with them unpleasant.

2. Statistical discrimination. You are aware that many personal traits which are relevant to you as an employer, landlord, teacher, waiter, or whatever, and which are not easily observable, are correlated with race. You therefore make probabilistic assumptions about a person based on their race.

3. Desire to help. You feel particular liking and sympathy for members of your own group, however defined, and when you know that some action of yours, whether purely altruistic or partially self-interested, will benefit another, you are more eager to do it if the benefit is conferred on a group you specially love. You may or may not be a member of that group yourself.

Now, it seems pretty clear that discrimination which proceeds from motive (1) is bad. But it’s not clear that discrimination from motives (2) or (3) is bad, and it might even be good.

It can be proved that statistical discrimination is sometimes efficient. As an example, consider the well-known complaint that it’s harder for African-Americans to catch a cab. This might be because taxi drivers are racist in sense (1), but I doubt it. More likely, taxi drivers are engaged in statistical discrimination. Cab driving is a rather dangerous business, because among patrons there are a few bad apples who might rob or even kill you. Doubtless, the vast majority of black taxi customers are law-abiding, but it is nonetheless a statistical fact that crime rates are higher among blacks, so the cab driver runs a greater risk. From an economist’s point of view, a smart solution would be to allow cab drivers to practice statistical discrimination by charging black clients more! The higher price would compensate for the greater risk, and blacks would have just as easy a time catching a cab. By that logic, explicit racial price discrimination by cab drivers might make the world a better place. But we’re unwilling to tolerate that, so cab drivers probably optimize by avoiding black clients. The somewhat serendipitous nature of customer-taxi contacts– Did he avoid me or did he just not see me hail him?— makes statistical discrimination difficult to regulate. Statistical discrimination in hiring seems harder to justify, since a job application and interview would seem to provide better information than crude racial patterns can supply. But maybe not. If Irish, say, are particularly sociable, or Asians particularly conscientious, it might be a profit-maximizing strategy to discriminate in favor of Irish people for head-hunters and salesmen, and Asians for analysts and accountants.

As for discrimination in favor of one’s own group, this has several things going for it. First, it seems like a good thing if one’s job isn’t just a paycheck, but is about making the world a better place. One way you might make the world a better place is by giving someone a service, or a job, that they love. But knowing whether they love the service, or the job, will have a lot to do with knowing them. Maybe you know via ethnic networks that your co-national Mr. X really needs the job, whereas you have no way to find out whether outsider Mr. Y does. Second, working with someone you like and identify with might just be fun, in a way that working with a stranger isn’t. Third, there may be a tacit “gift exchange” dynamic in hiring an insider, which is missing in the case of an outsider. In short, discriminating in favor of insiders may build social capital, the merits of which Robert Putnam has amply explained in his writings even if he is too much of a cheerleader for it.

American society has won a massive victory over racism in the past few decades. This is something to be proud of. It is, by and large, a step forward for justice. And yet in many respects it has gone too far, and impinged too much on freedom of association. I suspect that is part of the reason for the social capital decline that Putnam has exhaustively explored in the course of his career. Anti-discrimination norms in both law and personal ethics have severely restricted our ability to associate with those we like associating with. We have imposed an arm’s-length principle on the realms of commerce and to a considerable extent civil society as well, and paid the price in lost fraternity and neighborliness. It may be a price worth paying as regards blacks, who really were terribly oppressed for much of American history. That is something to atone for. But only in the case of blacks. Non-discrimination is not a general moral principle. It is only tenuously related to justice. It is not wrong to hire a family man, or a single mother, in preference to a bachelor or bachelorette, on the grounds that they need the job more, or are likely to be more stable. It is probably right to suppress the urge to engage in statistical discrimination with respect to blacks, even when that means sacrificing a bit of profit, though I think cab drivers who avoid a real risk of being crime victims by not picking up black customers are probably justified.

Now, let’s bring this back to immigration. With respect to immigrants, lots of discrimination with motives (2) and (3) will be warranted. Immigrants will often lack the language skills, cultural understanding, and perhaps values systems to be suitable for certain jobs or inclusion in certain clubs. More subtly but no less importantly, types of immigrants may tend to lack certain traits. It’s unfair, in a sense, if private discrimination denies to certain immigrants opportunities for which they are really qualified, simply because the groups of which they are a part tend to lack suitable traits. But we can’t make the world perfectly fair. And all the private discrimination on earth could never come close to the unfairness of migration restrictions.

It’s absurd to exclude a person from a country on the grounds that if he comes, he’ll face private discrimination. If that’s a price he’s willing to pay, let him. Very likely, the opportunities from which he is excluded, he wouldn’t have wanted anyway. Meanwhile, native citizens who are forced to integrate with immigrants– meaning, not just to see them on the street, which involves trivial harm and no violation of rights, but to be forced to hire them, rent apartments to them, accept them in a school, etc.– do have a valid grievance. Something has been taken away from them. Possibly– it’s an interesting question– the optimal world would involve both open borders and anti-discrimination laws, and native citizens should just be forced to integrate with all manner of immigrants, regardless of the psychic cost. One thing is clear, though: if we think native citizens should be spared from forced integration, the way to achieve that is to permit them to engage in private discrimination against immigrants, not to exclude immigrants by force from the territory of a country.

Open borders and Gilded Age success

In an article at The Freeman, “Bring Back the Gilded Age” (part 1 and part 2), I argue that the Great Stagnation is a result of the exhaustion of the technological legacy of the Gilded Age, of which I claim that:

In the decades before World War I, sometimes called “the Gilded Age,”  institutions in America and Europe were more conducive to progress than they are  today. Old bonds of class and custom had lost most of their power to lock people  into traditional roles. Absolutist and arbitrary government had lost ground to  the rule of law. The limited-liability corporation had taken shape and was in  the ascendant. In short, capitalism had taken command. But socialism, communism,  progressivism, fascism, the welfare state, migration control, and other bad  ideas that bedeviled the twentieth century were still young and weak. The result  was a mighty wave of betterment of the human condition whose momentum carried it  well into the twentieth century—long after the eclipse of the nineteenth-century  liberalism that had set the wave in motion.

One of the features that made the Gilded Age more conducive to progress was open borders:

4. Open immigration. “Give me your tired, your poor / Your huddled  masses yearning to breathe free / The wretched refuse of your teeming shore /  Send these, the homeless, the tempest-tossed to me / I lift my lamp beside the  golden door.” The famous Statue of Liberty poem, written by Emma Lazarus in  1883, is still sometimes quoted with some patriotic feeling, but modern America  is unworthy of it. Not only does the United States turn away the vast majority  of applicants for immigration visas, but it especially discriminates against the  poor, homeless, huddled masses whom the Statue of Liberty welcomes in the poem,  in favor of the highly educated. In the Gilded Age, though, it described a  reality. Not only the United States but all of the world’s leading countries  kept their borders almost entirely open to immigration then, not so much out of  generosity, as because the bad idea that it is somehow acceptable to exclude  peaceful migrants by force from a country through a comprehensive passport  regime had not yet darkened the mind of man.

Considering that the United States was absorbing so many low-skill  immigrants at that time, the statistics probably understate the superiority of  U.S. economic performance in the Gilded Age, since productivity statistics do  not even capture the jump in productivity that occurs when a person from an  impoverished country in eastern and or southern Europe joined the population of  the much wealthier United States. But immigrants also contributed to U.S. growth  in several ways. First, then as now, some of the leading entrepreneurs, like  Andrew Carnegie, and inventors, like Nikola Tesla, were immigrants. Nowadays,  many advocate discrimination in favor of “high-skill” immigrants, but Carnegie  was not “high-skill” when he arrived: He was born in a poor weaver’s cottage in  Scotland. Immigrants also supplied a mass workforce and a mass market for  factory-produced goods. A great theme of nineteenth-century capitalism was the  drive for cheapness, as goods once enjoyed by the rich became affordable for the  masses. Today, the world’s poor are kept out of America, so it’s harder for  American capitalists to make fortunes by serving them.

It occurred to me after I sent the article to press that Henry Ford and Norman Borlaug might serve as symbols of innovation with and without open borders. The two men are arguably the greatest benefactors of mankind in the last 150 years or so. Ford, by mass-producing automobiles and bringing them within reach of the common man, was the single most important contributor to the upsurge in living standards which occupied the first few decades of the 20th century. Borlaug invented disease-resistant and high-yielding strains of wheat that vastly increased food production in many developing countries, and thereby averted the major famines that would have occurred due to population growth, without these increases in agricultural productivity. Borlaug has been called “the man who saved a billion lives.” But here’s the crucial difference: Ford was financed by venture capital, and ended up an extremely rich man; Borlaug worked with governments and private charities, such as the Rockefeller Foundation, and as far as a little online research has revealed, he never got rich. Why not? Because when poor people can come to America, as did millions of immigrants who became Ford’s customers, they become a lucrative mass market; but when they are scattered all over the world and living under governments whose respect for property rights is imperfect, you can’t make much money by serving them. Borlaug is a more appealing figure than Ford for not being in it for the money. But free-market capitalism with sophisticated property rights protection incentivizes individual effort and private capital to benefit the public. See my post “Innovation and open borders” for more on this.
