" The effects of migration on poverty reduction dwarf those of free trade. Migrants who succeed in moving from poor countries to rich countries become better off than they were at home, and their remittances help their families do better at home. Remittances have very different effects than aid, and they can empower recipients to demand more from their governments, improving governance rather than undermining it. Of course, the politics of migration is even tougher than the politics of free trade, even in countries where the urge to help is most strongly developed. A helpful type of temporary migration is to provide undergraduate and graduate scholarships to the West, especially for Africans. With luck, these students will develop in a way that is independent of aid agencies or of their domestic regimes. Even if they do not return home, at least at once, the African diaspora is a fertile (and internal) source of development projects at home. "
