I think they are, and strongly.

The drive to achieve that level of success often comes from weaponized poor self esteem.

Well adjusted individuals just chill out after a few million and work on whatever is fun/important for them.

Only rarely does this also happen to be something that can take you from 10M to 1B. (and if it can it would take a lot of work you can't be bothered to do unless it's some core value like helping the poor beat malaria)

Trump saying recently that he hates hanging around successful people and prefers losers because he doesn't want to listen to other people's stories really speaks to the poor self esteem angle
