It's my impression that people who've achieved such immense wealth & power don't operate with anything resembling the moral compass the rest of us peasants do.
A peasant friend recently approached a billionaire pitching a service the billionaire could actually use. The billionaire proceeded to push & grind him down on price to save a few hundred dollars.
To me, if I had billion$, I'd like to think I'd be benevolent: "Hey, that sounds useful, and yes I'd pay for it!". It just seems you don't get to the top with kindness or charity.
