You're mixing individuals and groups in a way that I can't really say much about it. I was talking exclusively about individuals that I've known personally beyond sitting at the same table or working for them with three layers of indirection.

Fair enough, for me I suppose for me the vast majority of people are deep down terrible and only made good because they have been made to be. I can imagine what you say is very true and no doubt the vast majority of billionaires are horrible and their untouchableness no doubt makes that so.

But a lot of people the only moment they get to act in an unaccountable manor will act very badly. This is not all people but probably above 90%.

I think there is a level where you are no longer accountable in the way that ordinary people are accountable and I suspect that this is the reason why it happens, but my suspicions are worth absolutely nothing and given that these people are - in spite of the vast amount of information we seem to have about them - so in control of the narratives of their lives that it is impossible to make a diagnosis that will stick. So I will revert to the default: I don't know, but the sample I've seen makes me suspect that there is more to this than just coincidence.
