One thing that has crossed my mind before is that a lot of currently decent people might act very differently if they knew that wealth was awaiting them or could be significantly grown. For instance, when I first read and listened to some of what Elon Musk, Jeff Bezos, and Bill Gates had to say, they generally seemed like relatable and down-to-earth people. In a sense, they even seemed like role models in specific ways, if one were to focus only on how they presented and what they had achieved.
But then I read more about their history and the abusive practices, exploitation, and other unethical things they had done to help themselves make and grow their wealth. I was shocked to find out just how nasty and deeply unscrupulous they had all been at multiple points in their careers: mistreating employees (e.g., by overworking and underpaying them and, in Musk's case, firing them for disagreeing with him despite his claims of being a "free speech absolutist"), engaging in shady practices to evade higher taxes, unethically ruining competitors in order to monopolize the market, and, in Musk's case (again), topping off all of his other dubious practices with
baselessly accusing someone of pedophilia and
implying that another was supporting grooming—and this is not a remotely exhaustive list of the three men's excesses.
It makes me wonder how many people who may be currently decent could change if they found themselves in the same situation as Musk, Gates, or Bezos and had similar power and influence. It's easy to say that one would never be as abusive or nasty as those men have been on many occasions even if one became similarly rich, but it's much harder to know that with certainty or to know exactly how one would act under those circumstances. I like to think that I would still strive to live up to my values just as I strive to do so now, but I can't claim to be absolutely, unquestionably certain about how I would act in such a situation either.
