Black (ex-slave) immigrants from the Caribbean who live in NY city have a higher average income than the White majority.
I saw one of those immigrants quoted saying,"Isn't America wonderful, anyone here can get rich just by working hard".
For some reason American blacks think they are the only people ever enslaved in the history of the world. The entire history of the world consists of stronger cultures colonizing and enslaving weaker cultures, which are eventually assimilated.
