Plenty is doing.
"In Brazil....slavery was never as widespread as in the United States, and race relations are consistently described as better than they are [in the US] Yet the disparity between black and white incomes is greater in Brazil than in the US. Cuba also has a mixed population and is famous for its aggressive, socialist egalitarianism. Though Cuban officials are embarrassed by this and try to keep it a secret, blacks are invariably at the bottom of society. ....The Caribbean nation of Haiti presents an interesting parallel to the failures of black Africans. Its six million inhabitants are all black, the descendants of slaves. Haiti has essentially been governed by blacks ever since the slave insurrection of 1791, in which nearly all whites were killed. Thus it has a history of independence and black rule that is much longer than that of African nations. Despite such different histories, Haiti is practically indistinguishable from Africa in terms of GNP per caput, infant mortality rates, average educational level, and all the other indices of modernization. Its governments have been the corrupt shambles that is typical of Africa. If Haiti were dragged across the Atlantic Ocean and attached to the coast of Africa, it would seem perfectly at home."
