I've never known any really wealthy people but I once worked for a pretty wealthy guy. We were BSing in a car on the way to somewhere and he told me about having a childhood friend who was really well off. My boss said he had tried to hang but just couldn't keep up, or after a while even relate.
I'm a <50%er by birth and attitude. On my very best day I might have briefly glimpsed 10% but it was an accident.
My boss was a 1%er but even though born to a going concern he still had to work it, to whatever extent.
His friend was a born 0.1%er...
3 different worlds.
