This depends on the individuals' character -- when I look around, I mostly see people who become jerks/a-holes once they get money. Especially in the tech world. Look at what Google founders do with their money (evading taxes, mostly), or at others who became outright nazis and support far-right movements across the world. In the best case scenario they just keep buying yachts and villas and stay relatively quiet.
Mitchell is a beautiful exception and it makes me happy.
Perhaps this is an artefact of how people get rich or the types of people that are able to get rich in our world, not the mere fact that they get rich.
I think a lot of it has to do with how people get money. Not everyone, but a lot of people get a lot of money through very exchange-oriented ways and continue to be exchange-oriented afterwards.
I've always wondered what would happen if more people got a lot of money through more communal-oriented ways.
