Fair enough, even my generally frugal old money ancestors didn't hoard wealth like these bastards. They preferred to etch their name in stone by financing the construction of libraries and historical societies, hell one bank rolled the start up for a volunteer fire brigade bank rolled a quarter of their budged for 50 years. I guess that's kinda the key difference between the billionaires and regular folks be they rich or poor normal humans want to do shit and not sit around like a bunch of boring ass dragons.

Here's some anecdata: someone close to me became accidentally moderately rich (somwhere in the 50-100M range). Before that, he'd worked hard his whole life and endured hardship due to some of the usual problems that life throws at a working person. In the several years since the windfall, he has drifted from (by US standards) radical leftism to vaguely-leftish centrism. However, he does give away half the earnings on his wealth every year, and is very diligent in making sure that the groups he funds are efficient at delivering on their stated objectives. The programs he supports are soft-left and none of his money goes to anything remotely MAGA.

As for lifestyle: he moved to a bigger but discreetly anonymous house, replaced his ancient and rusting economy car with a more recent (but still second-hand) one, and he and his partner dine out more often than they previously did. No nouveau-riche glitz. If you saw him on the street, you'd assume he's a hippyish retired tradesman. So I'd characterize him as slightly warped by the sudden change in circumstance, but still self-aware.

Now, if a billion had landed in his lap, the warping power might have been proportionatey greater.

I like to think I'd be more resistant to the corrupting power of money, but like you, I don't know.
