Slavery,, did it not have good results for the ancestors of these slaves?

I think that is a really good thought provoking question. But you have to consider to that Africa was also affected by the slavery trade as well as being Colonised by European countries. In fact it wasn't until the late 20th century that South Africa was still under the complete control of European Colonists. But as an African American I can say that I am very happy and fill privileged to be born in America.
