Not entirely, its more a worry than an assertion, humanity's greatest strength is that it isn't a monolith so I'd figure YMMV. Its just when the jeering crowd point and shame others for being reprehensible, part of me wonders if all that crowd would pass that vibe-check if they'd been presented with that same opportunity. Is it morality, or is it just opportunity? Idk but I think its hard to prove either way.
So, true wealth removes the limiters and the consequences that might keep some people in check. It's like how, for all the horrors that religion foisted upon us over the centuries, one of the good things it did was to encourage a general populace to attempt to better people using the threat of hell and encouraging an acknowledgement of sin.
There's also some selection bias going on: in order to become obscenely wealthy, you probably need to lack some empathy and decency to beging with. Once you get there, these qualities can then flourish unhinged.
Based on my framework that means the moral tragedy occurred long before the wealth and fame.
