Anna Marina,
It seems the Africans were not able to compete with whitey when he came along. They were compared to whitey low tech and unorganised. They could probably teach the white man how to live of the land, what food and animals to grow and what to avoid, but that was not what whitey was looking for. Currently we have the situation in the US where the blacks (of course generally speaking) are much more criminal than the whites (12% of the US population are responsible for 50% of the murders, which is utterly shocking) and significantly less educated and productive (again generally speaking, we have white retards and a black Neil Degrasse). We can see what happened to South Africa after black man took over, not good. Currenly US blacks want to import the South African violence it seems. Then we have the whitey cultural marxism saying blame their inability on whitey, wow that is racism both ways
