Vast wealth can get out of hand, sure.

But for the most part, we as individuals earn money to better our lives. Get a better education, live in a better part of town, raise kids safer with better food etc. Its not a game, its life. Its also a mistake to say "money shouldn't determine important things like who gets to go to a good school", because money is exactly designed for that. Its not supposed to be just a game where money only buys toys and entertainment
