Capitalism works because it motivates. But thereβs no upper limit. No amount of profit will ever be enough profit, so unrestrained and unregulated, it will roll over everything until it destroys everything including itself.
Thatβs the point of progressive tax rates that used to go all the way up. You make it harder and harder to make more money and eventually itβs not worth it to people to keep trying. And in the meantime while they try, governments get money to mitigate the damage done to society.
