Leaving Haiti brought more Haitians out of poverty than anything else that has ever been tried...Obviously, the political calculus of mass migration is impossible. It seems to Global Review that the best way to loosen the migration constraint on the Haitian market is to rapidly disperse pre-earthquake orphans to willing adoptive countries. This is being done on a small scale, but is important for three reasons: children can pick up the language and culture of a new country quickly, and integrate seemlessly; orphans have the least to lose by leaving; orphanages in Haiti will need space for earthquake-created orphans, most of whom won't know for some time whether their families survived.
Of all the Haitians who live either in the United States or Haiti, and who live on more than $10 per day—at U.S. prices, adjusted for the fact that things are cheaper in Haiti—how many live in the U.S.? (That’s a barebones poverty standard, just one third of the U.S. “poverty line” for a single adult.)
82 Percent of Haitians above this poverty line are here in the United States. (I calculate this with Lant Pritchett here) Only the top 1.4 percent of people in Haiti had that living standard even before the quake, and there is no evidence that Haitian emigrants come primarily from the extreme tip-top of the income distribution. So for most of Haitians who left, leaving Haiti was the cause of leaving poverty.
In the moment of crisis and media attention, it will be much easier to find adoptive parents for some of Haiti's reported 380,000 orphans. That's a lot of people - but not too many for the developed world (especially Europe, with its low, low birthrates) to absorb.
