African-Americans are inferior to African-Africans

“at least as measured by enrollment in elite universities, black immigrants and their children are succeeding in America far more, on average, than blacks whose families have been in the U.S. for generations--i.e., the descendants of slaves. This is a strong argument against the proposition that black underachievement in America is primarily the result of present-day racism.”

Yay! The slaves were picked among the strongest and dumbest.

I've noticed that Africa-born niggers are on average a lot more polite, educated, well-dressed, hard-working and all around more similar to real human beings instead of parasitic beasts like the niggers born here.

Maybe it's selection bias, since most current african immigrants are usually moderately skilled people looking for a future abroad, instead of some tribesmen captured to work on cotton farms or crossing the mediterranean on nigboats.
