Billionaires are generally stupid and idiotic in any case.
They blame their problems on poor people, taxes and governments and convince people to agree. They did not make the money from much effort of their own, generally speaking.
Look at it dispassionately and logically. You don’t work harder when you make more money. You work less and less and less as you delegate and rise up in income.
The billionaires do nothing at all but talk and even that’s optional. Lazy.
