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.
