Immigration policy is one of the most important areas of global development, as an open borders regime would dramatically reduce poverty and grow the world economy by up to 150%. Open Phil devotes some funding to immigration policy in the United States; however, the Trump Administration has been extremely hostile to immigration, and it seems wise to spread our effort across several countries in order to loosen immigration policy around the globe. Which countries would be the best places to advocate for more permissive immigration policy?
I don't have an answer to which countries would be more receptive to the idea, definitely don't try here in Israel!
I am however interested in the claimed effectiveness of open borders. Do these estimates take into account potential backlash or political instability that a large number of immigrants could cause? I understand that theoretically, closed borders are economically inefficient and solidify inequality, but I fear that open borders could cause significant political problems and backlash. Even if we were to consider this backlash to be unjustified or immoral, we need to keep it in consideration when thinking of the effects of this policy. Am I unjustified in thinking that significant negative political effects are possible?
I think these concerns are valid. The website Open Borders: The Case addresses many of the main arguments against open borders, including the possibility of nativist backlash to increased immigration.
"Nativist backlash" refers to the hypothesis that a country opening its borders to all immigration would cause a significant portion of current residents to subsequently turn against immigration. The problem with this claim is that the probability of backlash depends on how a country adopts open borders in the first place. Nathan Smith writes:
