It's racist period, in the past all racial groups were involved in some form of behavior our modern society would call barbaric, it is a product of human ignorance. Slavery, genocide, human sacrifice, "stealing land", rape, incest, child rape etc were all carried out in Africa. So whatever someone rich there has , the same thing can be said about them, white people simply parlayed their evil into viable institutions while other groups haphazardly did evil, but there were no saintly racial groups.
