I know a number of wealthy folks, many of them, actually really decent people. They deserve their wealth, and I have no issues with it. They tend to have somewhat different value systems than I do, but we get along, anyway.
I have learned that one word they pretty much never hear, is "No."
Even the very best of them, gets used to having every whacked-out fever dream their Id squeezes out, treated like God's Word.
People who aren't very good at self-analysis and self-control, can have real problems with it.
We are watching a bunch of very public examples of exactly this, right now.
