The children of very accomplished/wealthy families need extra watching because of the difficulty of matching the accomplishments of their forebears. You can be anything? Can you become a billionaire? What is extraordinary about Donald Trump is that he not only matched, but exceeded his father’s financial success (who died with $200m to his name) *and* got elected to the White House on his first try. The latter is like getting a hole-in-one the first time you pick up a golf club. Trump made it look easy. Bloomberg showed it isn’t, a billion dollars later. Meanwhile, Bloomberg’s children are trust fund wastrels whose principal occupation is spending his money through various slush funds dubbed charities that are under their control.
You’re right, though I would note that J. Paul Getty, like Donald Trump and William Randolph Hearst, was himself a 2nd generation rich person. It’s absolutely true that the children of the extremely wealthy are at great risk of becoming wastrels, but Trump follows a pattern of *some* rich offspring who parlay the previous generation’s wealth into something even grander. To lesser extent this is also true of people like Warren Buffett, Bill Gates and Mark Zuckerberg who were born into moderate wealth and became uber-rich. It’s really the 3rd and 4th generations of the rich people who seem to be at the greatest risk of screwing up. And then when you get to like 12th generation of extreme wealth like the DuPonts some real eccentric wackos are more the rule than the exception.
