Why isn’t enough, enough for the rich?

My question is when is enough enough for the rich in American. At what point have you basically “won capitalism”, take your victory lap and enjoy the spoils of your hard work, step aside and let the next person take their shot.

Again this is (my take) why the Uber rich should be hammered with taxes. Don’t want to pay a ton a taxes, stop raking in tens of millions of dollars every year that you’ll never spend in 3 generations. Maybe then we can lift the standard of living for everyone, not just specific classes.
