You may find that the black people they favor are also privileged. IE a Nigerian 1-percenter is just as black for affirmative action metrics as an African American from a broken family living in inner-city Baltimore, but the Nigerian is probably 1000x more likely to be accepted into an American college.

Yes exactly. That is why the diversity metric that would actually alleviate the situation of poor blacks like being income based is NOT used as that would also cripple the rich white elites.

I never understood this. Imo the moral justification behind affirmative action is that the upper echelons of society should represent the demographic makeup of society in general. Importing people who look like the people who you try to represent is the opposite of representation.
