It is also easy to forget that the suppliers of slaves were African nations that practiced slavery themselves. They found the Europeans to be great customers for their slaves. So descendants of the Ashanti and others benefited from the selling of slaves. If we really want to look at reparations, we probably need some way to determine what percentage each person benefited from slavery and what percentage they suffered from it. Also there were slaves from Asia and other places that are probably just as deserving of payments if that happens. But all of this flies in face of the narrative that slavery was something whites did to blacks.
A better approach would be to try to provide opportunities that people can take advantage of. The US actually does a great job of this which is why we don't see mass exodus of people trying to go back to the African nations.
