Because rich people and poor people didn't exist 200 years ago or 500 years ago or 1000 years ago, amirite? Everyone was equal until the horrible capitalism was invented? C'mon son. If it's not money it'll be skin color, if it's not skin color it'll be height, if it's not height it'll be size of dick or boobs. There will ALWAYS be something.
Even on animal societies without the horrible horrible technology or rich people and poor people there's discrimination. If it's not domination through wealth then it'll be domination through physical power and if not by that then it'll be any other whatever arbitrary thing.
