Eh, you don't hear about the ones who are well adjusted.

Usually nobody cares if you're a poor jerk. At least unless you do something phenomenal you don't get wide attention.

"New" rich people, especially those with power over other people, can develop plenty of complexes and insecurities that come out as weakness... like firing somebody for mocking them.

"Old" rich, generational wealth tend to develop a set of manners and habits where they don't get noticed or embarrass themselves quite so much by displaying such weakness.

You don't stay rich for a long time if you act like a fool.
