Are you and the top level comment saying that rural/midwestern poor white americans are competing for jobs against wealthy black americans? I'm just trying to understand what this sentiment means, not trying to be combative or anything
Speaking for myself, I'd discuss things like affirmative action in college admissions, whose advocates would admit a wealthy black person from a prep school before a poor white person from a failing rural school who has better test scores, and call that "social justice".
But you are repeating and justifying this comment up and down the thread.
I can't speak to exactly what the original author of the remark meant by those words specifically.
