When one group of people has all the money and all the connections, it’s not fair to say “just treat everyone equally!” because it maintains the unequal status quo
Then targeting socioeconomic status makes more sense. Any system that categorizes people and puts poor white folks in the same “has all the money and connections” bucket as the Clintons and the Obamas in the same “has no money or connections” bucket as poor black folks is not, in any way, actually about having money or connections.
