Using Bezos as an example - an interesting proportion would be something like: how many customers (eg, people who find his work valuable) does Bezos have versus an average American? How many people has Bezos employed and made successful (or at the very least, gave them a better job than they would have otherwise?) vs an average American.
To wit, it doesn't make sense to compare "wealth" without also talking about "impact" in a case like Bezos.
The other ignorant thing is this makes it seem like his wealth is some sort of zero sum game where if he has a dollar that means you don't have it. The reality of his wealth is something like this: he owns a chunk of Amazon, AND Amazon has grown to be valuable and valued. The same guy, had Amazon gone nowhere, would have nothing. The mechanism of him becoming rich is primarily the world collectively deciding that the thing he has built is valuable, rather than him taking dollars out of your pockets.
Why does this bother me? Because I find things that breed resentment in the world to be a detrimental evil.
