How do we translate the cause of open borders into specific policy recommendations? The range of policies entailed by “looser border controls” is wide — and the range of policies which might be mistakenly attached to the “open borders” idea is even wider. It is important to be clear on definitions when we discuss the idea of open borders, lest we waste time on proposals which few actually support.
Before I continue, note that I speak only for myself; not for Vipul, not for Nathan, and not for any other advocate of open borders, even though we all support greater immigration. In fact, immigration supporter Tyler Cowen declares himself opposed to open borders, even though I suspect under my definition of “open borders”, he may be one of our greatest advocates.
It is crucial to be clear about what “open borders” really means in terms of end goals. Being vague about the meaning of “open borders” makes it easy for restrictionists to attack straw men, while ignoring the strongest arguments for open borders. So when I seek open borders, here is what I want: people to be able to cross international borders at will, insofar as this is administratively practical.
