Migrating to Prosperity
Michael Clemens, an economist and Senior Fellow at the Center for Global Development, argues that unrestricted migration would add more to global economic output than any other public policy option, a lot more. Even modest reductions in current barriers would add more to world prosperity than complete elimination of restrictions on the free flow of goods and capital.
Clemens says between 40% and 60% of people in poorer nations would move if they could. The able bodied among them would be more productive if they did. He cites studies that suggest total world output could increase by anywhere from 60% to 150%. Partial easing could yield maybe 24%. That's a lot of trillion dollar bills lying around on the sidewalk.
If Clemens is right we could be talking about an end to poverty once and for all. It could happen. For all the harsh rhetoric of late the US remains one of the wealthy countries most open to immigration today. Europe is more open than it was thirty years ago. Japan is one of the most restrictive, but has an aging population and will most likely be forced to open up more. And mass migration has been a regular feature of the human condition for all of history. The time may be ripe for another one.
Usually when the subject of third world poverty comes up we talk about addressing it with foreign aid. Aid can be helpful but its impact has always been limited and much of our foreign aid is military. Remittances seem to be more effective. Even a low income immigrant sending home a few dollars a month can make a big difference to a poor family. The biggest factor in reducing poverty in recent decades seems to have been international trade. It has made it possible for billions to move into the middle class.
Most economists estimate that completely free and open trade might add about 4% to economic growth. The numbers Clemens throws around are higher by an order of magnitude or two. We should be paying attention. We aren't about to dismantle our border controls and nobody is suggesting we should. But this should be a part of our national discussion on immigration reform.
There are some practical things we can and should do. Our graduate schools have been pleading for years to be allowed to accept more foreign students. We should make it happen. More than a few have stayed and started businesses, creating jobs, well paying American jobs. We have a chronic shortage of medical professionals and from everything I read it is only going to get worse. Why on earth would we reject a visa application from a qualified nurse who happens to be from Nicaragua? Yes, we would prefer to fill those jobs with native Americans (I use the term in its proper sense, not its politically correct sense) but when you need a nurse, you need a nurse.
The issue should be prominent in the international human rights discussion too. The church has a role to play here. Pope Francis was on the Italian island of Lampedusa this month praying for the thousands of Africans who have died trying to make their way to Europe. I can only imagine what he will have to say when he comes here. Rome has been an active observer at international trade negotiations (so has the USCCB,) always advocating for the interests of the poor and vulnerable. A desperate migrant risking his life to get to a place where he can find a decent job would certainly qualify as poor, vulnerable, and in need of an advocate. Some of those migrants on Lampedusa are unaccompanied children sleeping on the ground because there is no shelter.
