The answer is that we owe Negroes nothing.You sre dodging the question.
Here are some questions for you. Why are American Negroes better off economically than Negroes in black majority, black run countries?
Would American Negroes be better off if all the whites left? If your answer is "Yes" why have conditions deteriorated in Sub Saharan Africa since African independence and the end of apartheid?
Would whites be better off if all the American Negroes left? I think we would be. The crime rate would go way down. The cost of our criminal justice and welfare systems would decline.
