They would be richer, but by “allowing” working class people to have a thriving life means the power gap between us and them wouldn’t be as big. People could organize and overthrow them, so they have to keep us fighting amongst ourselves for scraps.
The cruelty is the point.
I remember reading that when national parks tried to make a ‘bear-proof’ trashcan, they found that there was a larger overlap between the smartest bear and the stupidest human to make a viable product.
I feel like it’s a similar situation here. The smartest kid and the stupidest adult are far more similar than we’d like to admit.
