Just to take any talk of genetics off the table, I want to be a witness to the fact that, in my 10-plus years experience as a college teacher, my brightest, most interesting, and most hardworking students were African immigrants, especially from Nigeria, which seems to be factory of human talent that has enormously benefited the USA.

I agree. This is inner-city culture. I find that inner-city Hispanics are starting to act similarly, but recent immigrants from South and Central America don’t. Ditto the few African students I have had.
