There has always been inequality, and within every species.
American universities admit black students at roughly the same rate as white students, but the graduation rate for black men six years after matriculation is just 40%, vs. 70% for Asian men and 62% for white men. We blame their failure on "micro-aggression" (but don't explain why black women, who presumably are more oppressed even than black men, have a much higher graduation rate).
I think that last one is fairly easy to explain: Black women take the kind of courses it's easier to pass. Like, Black Women Studies. And some black men don't really need to graduate in the first place...they just move on to the NBA or NFL...
