But this is based on your projection that having "more money than he knows what do with" produces happiness and that if you have a diff philosophy you're a fool.
Buddha, Jesus, Mohammed, Lao Tzu, and just about every other spiritual teacher that ever existed in reality or myth, would all qualify as fools by your definition as none of them believed that money could possibly produce happiness.
If you're right that might make IG posters, shallow clout chasers, and other materialists the wisest among us.
Some would suggest this is foolishness as well. It all depends on your philosophy of happiness. But I haven't seen anything from rich ppl that suggests to me that they are happier than poor ppl tbh.
