Echoing @jimmysong, I think a lot depends on the existing moral foundation, plus the age at which you get the wealth.

like if you gave me a million+ dollars (or ten million, whatever), no strings attached now, my life would basically not change, I would still do the exact same things, play the same games etc. I would maybe get a nicer car and finish off the various garden construction projects.

But if was 15 or 20 at my peak retadrd phase, I probably would have made generally bad decisions, maybe not all bad, but possibly majority bad. I may have become a douche also, I like to think I wouldn't have, but who knows
