I have several successful middle class friends who are black. They all function on solid conservative values (hard work, family, church), which is the reason they are successful.
Unfortunately, I see plenty of the opposite. The father of one young man I know had fifteen children with three different wives, used drugs, was abusive to his children, and spent time in prison. It's amazing that he has turned out as well as he has.... I have to credit his Mom for doing a good job under crappy circumstances. Sadly, his younger brothers/sisters aren't doing so well. The daughter of another friend was harrassed and taunted in our local High School because (1) she is studious, and (2) had friends outside her racial group.
It's time to operate on the principle articulated by Erich Fromm, a Jewish psychologist who survived the death camps..."there are two human races, the decent and the indecent".
I like that.
