Go to small towns in the south and see how white people live. Poor is poor.
Disclaimer: I've only really lived in TN, and NC in the south and rural NY in the north. In laws are in small town IA (which as a southerner I classify as "north").
What I disagree with is the idea that we can cancel this racism and sexism out by giving them advantages in the big cities. Life should be based on merit, not genetics.
