In academic philosophical circles, Joseph Carens is well known as a proponent of open borders. His 1987 article Aliens and Citizens: The Case for Open Borders was included in our pro-open borders reading list since around the time of the site launch, and co-blogger Nathan blogged about the paper back in April 2012. We’ve referenced Carens quite a bit in subsequent blog posts.

I recently learned that Carens has given the philosophical issues surrounding migration the book-length treatment they deserve in the book The Ethics of Immigration (Oxford University Press, 2013). This is the first book-length treatment I’m aware of that deals with migration from a philosophical perspective and is written by a single author (UPDATE: As Paul Crider points out in the comments, Philosophies of Exclusion by Phillip Cole is an earlier book on the subject that I’d forgotten about. I haven’t read it, though). I was quite excited to hear about it, and read it with great eagerness. I found much food for thought in the book. In this blog post series (which may have two, three, or more parts, depending on the amount of material I end up wanting to write up) I will go over the parts of Carens’ book I found most interesting.

#1: Broad strategy followed by Carens

The book is not largely a defense of open borders. In fact, while the author does defend open borders, this is only a couple of chapters near the end of the book, and these chapters operate on somewhat different starting assumptions from the rest of the book. Rather, Carens spends the first ten chapters arguing within the status quo framework, i.e., assuming that it is just that the world is carved into nation-states and that states can exercise significant discretionary control over migration, but he also assumes that these are constrained by what he (inaptly?) terms “democratic principles” — more on that in #3. In the last four chapters, he critiques the status quo itself, and argues for open borders. He also defends himself against the charge of Trojan Horse-ing his way through. Chapters 1-8 come to many mainstream pro-migrant but migration policy-neutral conclusions, while Chapters 9-10 argue for for the right to family reunification and some rights for refugeees. Echoing Nathan’s view that a strong case for freer migration and more migrant rights can be made from communitarian premises, the bulk of Chapters 1-8 argues for migrant rights on communitarian grounds. This isn’t surprising, because communitarian grounds may be the only defensible framework that can simultaneously justify nation-states in the broad sense while still being compatible with moral egalitarian conditions. Roughly, the worldview Carens embraces is that everybody is equal, but many aspects of people’s rights are membership-specific (in relation to their communities) rather than universal moral claims, thereby permitting differential treatment (in some respects) by a state of tourists, temporary migrants, permanent residents, and citizens.

#2: Alleged target audience

Carens claims that his book is targeted at the median resident of the democracies of Europe and North America. This is an improvement over most migration-related books, that are often singularly focused on one specific country. However, I found Carens’ claim disingenuous in two ways:

• I don’t see a good reason why universal moral arguments should not be applicable to people outside Europe or North America, and Carens’ limited targeting may be viewed as a version of the soft bigotry of low expectations — i.e., that people in India or Malaysia or Australia or Japan or Saudi Arabia or Singapore or Hong Kong or the UAE need to be held to a lower moral bar with respect to migration policy. Carens occasionally cites policies in places like Singapore, Hong Kong, UAE, etc. as policies that no sensible country devoted to “democratic principles” (more on that catchword later) would follow. Contra Carens, I believe not only that the case for open borders is universal, but also that any case that can be made for or against various migrant rights is universal.
• Carens gives too much credit to the median resident of Europe or North America. The median resident doesn’t buy tracts from a university press that spend 300+ pages pondering over philosophical questions. About 15% of Americans are judged college-ready, and my guess is that the college-readiness benchmark would be a rough minimum to get through Carens’ book (you’d also need to be very interested in the subject). There’d of course be exceptions, but the percentage would overall be less than, not more than, 15%. This per se isn’t worrisome — authors often claim that their works have wider reach than they actually have — but it’s related to other things problematic about Carens’ logic.

#3: The “democratic principles” catchphrase

Carens uses the catchphrase “democratic principles” to describe beliefs that the median resident of Europe or North America might hold, but which seems to me to be (largely) shorthand for the ethical intuitions that people Carens interacts regularly with hold. To be clear, I’m no expert on the median person either, but a lot of the claims that Carens makes about how ordinary people think seem a bit off to me, judging by polling data I’ve seen. I feel like he’s slippery in roughly the same way Michael Huemer is when making claims about reasonable starting points for intuitions that most people hold.

For instance, Joseph Carens argues that it is obvious to any observer today (or at any rate, any observer who is faithful to “democratic principles”) that the Chinese Exclusion Act (CEA) was wrong, because it is obviously wrong to discriminate on the basis of nationality. While I agree that the CEA was wrong (see this lengthy blog post by co-blogger Chris Hendrix), it’s unclear to me that it’s significantly more “obvious” than open borders at large. If you embrace the principle that it’s wrong to discriminate on the basis of nationality to the point that the CEA is obviously wrong, haven’t you more or less embraced open borders (insofar as closed borders discriminate on the basis of nationality in a fairly fundamental way)? Further, to the extent that the CEA is condemnable on the grounds that it discriminated between different foreign nationalities, couldn’t the same be said of free movement within the EU (in that it discriminates between “other EU countries” and “non-EU countries” in its admissions policy)? Empirically, too, it’s unclear that people today have a strong view against the Chinese Exclusion Act. My impression is that the majority of Americans, if polled today, would be largely indifferent and consider it morally acceptable (even if unwise), rather than recoil in horror at the idea that such an act was passed a while back.

The remaining points are all arguments Carens makes presupposing the status quo framework, not necessarily ones he supports in reality, though every argument he makes moves in the “pro-migrant” and/or “open borders” direction once he takes off the hat of presupposing the status quo.

#4: Carens’ argument in favor of local legal equality

In a bow of sorts to territorialism and local inequality aversion, Carens argues that the same legal rules should apply to everybody within the physical territory, as opposed to a multi-tiered legal system. Carens does not propose an actual set of optimal policies, arguing that doing so would be outside the scope of the book. Rather, he uses a meta level argument. He argues that when a government (at a national or provincial level) chooses policies based on a balancing of considerations (e.g., choosing a minimum wage or labor regulation) the optimal policy that applies should be the same for natives as well as non-natives. Therefore, it makes no sense to have different labor regulations or policies for citizens and non-citizen permanent residents and temporary workers (a different policy for tourists is acceptable, because they’re not supposed to work). For instance, if minimum wage requirements are wrong, then they should not be applied to citizens either.

I see two objections to this, the first of which Carens anticipates to some extent, but the second he does not:

• It can be argued that different subdivisions of the population based on citizenship/residency are statistically different, so the best balancing of interests would suggest different optima for them. This can be analogized to how the optimal labor regulation changes with time — changes with time change the nature of the labor work being done, or the skill level, and therefore change optimal labor regulation. Similarly, different segments of the labor force have different labor needs and different optimal laws.

  Carens addresses this (largely in implicit fashion). He argues that segmenting the force this way is not appropriate, any more than having different labor laws by race is appropriate. If different laws are needed, they should be based on the relevant criterion — occupation or skill level — rather than migration status. To the extent that natives and migrants have different optima, the best overall optimum should be considered.

  This, however, raises an interesting point that Carens does not acknowledge. To the extent that migration policy changes the composition of the labor force, it changes optimal labor policies for the whole labor force. If you’re having a single general minimum wage, and the value of the minimum wage depends on the skill level of the population as a whole, then if large number of people at low skill levels migrate, this could move the optimal minimum wage downward (for instance), for the population as a whole, including natives. Carens’ tone seems to suggest that the optimal policy can be determined just by looking at natives, and once non-natives are added to the mix, they just get subjected to the same policy. But if you’re insisting on one policy for everybody, it needs to take everybody into account. I don’t know if Carens would disagree, but he doesn’t really acknowledge the implications of this (so far) — the idea that changes may need to be made to regulation that move the First World in a potentially “Third World” direction to accommodate the changing composition of the labor force. This seems like the only reasonable alternative to having a two-tiered regulatory system. (As an interesting aside, opponents of expanded migration under the status quo, such as the otherwise pro-migrant Ron Unz, often support increased minimum wages as a way to deter migration).

• Even if you believe that the optimal policy is independent of the population, the fact that the optimal policy for citizens is the same as the optimal policy for non-citizens doesn’t imply that the current policy for citizens (or for non-citizens for that matter) is close to that optimum. Therefore, moving the current policy for non-citizens in the direction of the current policy for citizens doesn’t make sense unless you already believe that that direction is the same as the direction of optimum. To take an example, suppose you believe that labor regulation X is bad (for everybody), but X applies to citizens currently. You have the opportunity to decide whether to support “not X” for non-citizens. Should you do that? (This also relates to the next point).

#5: Symbolic significance of reasonable measures undertaken in response to anti-immigration sentiment

Carens notes that there may be measures that are not wrong in substance but that have the symbolic significance of being anti-immigrant. He (tentatively) cites the UK’s tightening of birthright citizenship laws (to prevent tourists’ kids from getting such citizenship) as one example of such a measure. He doesn’t see the end result as morally wrong — he doesn’t think tourists’ kids prima facie deserve citizenship, but he believes that the move was in response to anti-immigrant sentiment.

To take another example (not provided by Carens), suppose you’re one of those who believes that “welfare creates a dependency trap that hurts its recipients more than it helps.” Would you vote for a ballot measure that sought to deny such welfare to some subclass of non-citizens? In your view, this denial would be in the non-citizens’ interest, but most likely the symbolic significance of it, and the perceived message, would be that the non-citizens are unwelcome.

#6: Against occupation-specific work visas

Carens offers an interesting argument against having occupation-specific work visas (i.e., work visas where the workers are restricted to a particular occupation). I don’t remember seeing the argument in that precise form before, though on this site we’ve obviously argued for a much more expansive vision of free movement than tying workers to a specific employer or occupation (see here for instance). I’ll take the liberty of paraphrasing Carens’ argument in a manner that will make both the argument and my subsequent critique of it clearer.

Consider these three types of prices of farm work:

1. The price that farm work commands in the native labor market, without migration.
2. The price that farm work would command if foreigners were free to migrate for work without being tied to an occupation.
3. The price that farm work would command if foreigners could be hired to come on a visa restricted to farm work only.

Carens’ point is that (2) would be greater than (3), i.e., if workers had the option of competing on the entire labor market, they could probably command higher wages for farm work. Though Carens doesn’t explicitly say it, his language suggests that he thinks that (1) ~ (2), so that having occupation-restricted work visas distorts prices quite a bit, more than closed borders do. I think the point is theoretically interesting, and regardless of the empirics, is yet another reason to argue against occupation-restricted work visas (though they may still beat out closed borders). Going into the empirics would be too much of a distraction in the context of this post, but it would involve looking at the general issue of the impact that migration has on native wages. To a first approximation, wages are likely to fall in the sectors that experience heavier migration and rise in the other sectors. To the extent that workers are free to move between occupations, both as a matter of law and as a matter of skill level, this would ameliorate the sector-specific wage effects, so Carens’ point does seem to have prima facie merit. However, I still wouldn’t hinge the case for open borders on the general claim that (1) ~ (2), because it is quite possible that even with workers being legally free to move between occupations, wages for some sectors, such as farm work, do fall significantly.

This isn’t the end of my commentary on the book. I’ll be publishing part 2 of the commentary sometime in the next month.
