Yes, they are different: People who care about others are less likely to become ultra rich. You become ultra rich by mostly caring about your cut and your profits.

While there are exceptions with people who were lucky and were at the right spot at the right time, there is a different distribution of character traits compared to society at large.

I invite you to expand on your blanket statement. I posit that the ultra-wealthy are necessarily and unavoidably transformed by the lived experience of having that level of wealth: virtually any logistical inconvenience you and I currently relate to can be monied away; the proportion of strangers and near-strangers that want to interact with you deferentially and transactionally jumps; the consequences for many of your mistakes become invisible to you.

edit: I don't mean just to shoot you down here--I think there's a counterargument to be made here. It might start with "those folks really are the same as us, responding and acting as we ourselves would when dropped into that environment and surroundings". That would hinge on observing the actions and behaviors of someone who, having lived a life as a billionaire, has lost or forsworn that level of fortune and whose lives we might now judge as in the range of "normal". I think that'll be hard to find; the wealthy making public pledges to give away 99% of their wealth are still ludicrously wealthy, and to my knowledge all make that commitment to do so around when they die--not before.

I agree that the consequences are greater. There seem to be at least two perspectives on whether wealth makes you different:

1. In 1926, F. Scott Fitzgerald wrote that the rich “are different from you and me,” and Ernest Hemingway supposedly retorted, “Yes, they have more money.”

2. Kurt Vonnegut's obituary for Joseph Heller...

True story, Word of Honor: Joseph Heller, an important and funny writer now dead, and I were at a party given by a billionaire on Shelter Island. I said, “Joe, how does it make you feel to know that our host only yesterday may have made more money than your novel ‘Catch-22’ has earned in its entire history?” And Joe said, “I’ve got something he can never have.” And I said, “What on earth could that be, Joe?” And Joe said, “The knowledge that I’ve got enough.” Not bad! Rest in peace!”

Or, as Cyndi Lauper sang it, 'Money Changes Everything'

I'm of the latter persuasion, that wealth influences one's personality in important ways.

The nature of the ultra wealthy is obviously no different than the rest of us - but the nurture and environment they live is in extremely different. That they live so isolated from the broader human community, are so disconnected from routine discomforts, and so shielded from any kind of consequences is an obvious difference from the rest of us. It’s no wonder they develop sociopathic tendencies when they are materially rewarded for such behavior and have no empathy for the way the rest of us must live.

>The ultra-wealthy are no different from anyone else

The ultra wealthy are very different from anyone else. First of all, their focus gets to be about power, everyone else's is survival and making the rent. Second they have armies of ass kissers. Third, they have no job and can even own politicians. And of course their wealth isolates them from repercursions anyone else would face, and puts their experience way out of phase with the regular people.

And we should also account for the sociopathic drive that made them rich in the first place (sociopaths are overrepresented in higher status positions).
