My wife chats with her friend over the phone fairly often, her friend has "problems" like we all do, just paying bills isn't a problem for her of course. We used to stay on her "estate" in France but she sold it, we stayed in a guest house on the property. Some aspects of being wealthy strike me as negatives regular folks don't really suffer.
Anyway, I think the vast majority of US billionaires try and live quiet lives out o0 the public eye.
