I must point out that African-Americans with college degrees earn less, on the average, than white Americans with high school degrees.
I don't know where you got that information, but according to this graph:

(based on '03 census) that's not even close to being true. Whites with HS education: $28,000 vs. Blacks with college education $60,000.
However, we agree that race/class discrimination remains a factor. My point was only that proper education, language, dress etc. can be a huge benefit for anyone of any race/class.
