Why do otherwise intelligent people with enormous wealth dare to think someone would want them for anything but mercenary motives? Even Donald Trump is wiser than that and treats hoes like hoes. No shame in that game because everyone knows the rules, one of which is direct bluntness (like referring to hoes as hoes, which is not hate or even dislike but observation) to prevent any illusions about those relationships.
Rich old men should hire successful pimps to give them reality briefings, because no one understands humanity like a master manipulator. The world is a very bad place but its worse for the naive. Elizabeth Holmes was able to manipulate men who would have known better were she a man.
It's degenerate to allow yourself to be unworldly. Ignorance is no virtue. The price of wealth is you are not a person to others (unless they're your homies from before you got rich, and that's subject to their avarice), just potential prey.
Old men especially should be completely cynical and jaded unless they're mentally ill. Not even kidding. Attractive people who are self-sufficient want other attractive people. Grifters want old men because they know old men are likely horny, desperate and vain.
