There are upper and middle class Africans. They have physicians, accountants and every other type of professional. They are just not controlling the wealth of their natural resources. Have you ever been there?
"While it certainly wasn't a favor to bring Blacks here"---you should have left it there. How do you know what Blacks would have made of themselves if they had not been kidnapped and enslaved? Answer: You don't know. What we do know is that enslaved Africans helped create the early wealth of this country. So, their descendants deserve reparations for their free labor.
