I worked in some of the fanciest tech companies for a long time, so I met people making up to $400k/year who were pretty cool. The cool ones tend to quit very quickly though, since that much money rapidly pays for a nice house and a retirement, and people who want more than that are messed up.
I don't think I ever met anyone who wasn't a psycho above that line. Often amiable psychos, who you could have a normal conversation with. But something has to be pretty deeply wrong with you if you're making $1m/year and you're not retiring immediately. And you don't even get to that point unless you worked through years of a lesser shitload of money (should've retired already), have some sort of nepotism connection (ie raised into moneyed psychopath culture), or are just a transparently cutthroat monster.
(These are all wages from working, btw. I have no doubt that the cutoff is lower for people living off other people's labor.)
