I know several black people with advanced STEM degrees, and they all have two things in common: (1) They were born in Africa or the Caribbean or they are first generation American born to parents born in Africa or the Caribbean (who act like real parents); and (2) they don't have a lot of respect for blacks who spend generations in the welfare system and blame others for their failure to take advantage of education and advancement opportunities.
I have relatives who taught school in Africa. They say African blacks hungered for school. Their students walked 3-5 miles and the school had no electricity. But they CAME.
