For some strange reason all those righteous, civilized, healthy and well-educated people from Africa and the ME leave their prosperous homelands behind and risk their lives to come the West and live among white racists. I know I wouldn't want to live among people who hate me, but they apparently do.
You are actually pointing something interesting.
One thing I have observed when travelling overseas, is the mass media in third world countries brainwash people into believing that to prove they are successful they need to live in the West.
I don't know if you know the power of the mass media.
