Your idea of "justice" is based upon group membership, as unfortunately for many other people. I see absolutely no difference between a poor white person vs. a poor black person. Sure, there might be
more poor black people, but so what? Do you seriously believe that rich white people would actively be trying to help poor white people and not poor black people? No, everybody wants riches for themselves, poor whites aren't given anything either.
This is what I tune out of the conversation whenever someone mentions "patriarchy" (the "modern" version, i.e. "men are in power" not "men own women") - I'm a man, but I've never received any benefit just because (most of) our presidents / businessmen are men (in fact, arguably (individual) women receive more benefits, because most of those men are heterosexuals).
