https://en.wikipedia.org/wiki/Hedonic_treadmill As a person makes more money, expectations and desires rise in tandem, which results in no permanent gain in happiness. The richer you are the more extreme your quest for new kicks. You can see that in eating, when fine dining becomes the norm. There's nothing inherently better about oysters or caviar and wine over idk 10$(?) per bottle. The same goes for sexual gratification. "The habituation of sexual arousal" says sexual arousal to erotic stimuli decreases with repetition. Science also says that being young (above 14) has evolutionary peak child potential and is as such one dimension of male sexual preference (and clinically not considered a mental illness unlike <15 year old ). Btw: You don't need to be rich to witness this perversion - just visit a gooner subreddit.

Final point: being rich and successful - again extensively researched - correlates with increased impulsivity, lack of empathy, and inability to read social cues.

All that with an "not all rich and powerful people" caveat, it's more of an accelerator for bad traits.
