Thanks for your rational response. I think what you're describing is very much the point, and I'd be lying if I said I didn't
feel it a bit myself.
But if there exists a tiny set of super-rich people, that only affects our perceptions, and doesn't do anything to actually make our life worse. Most of us will never even come into contact with the stratospherically rich; why should their theoretical existence bother us?
Disproving my own point a bit... I actually do regularly come into contact with one such person. My employer is a billionaire (or so says Forbes magazine), and I interact with her regularly. But, believe it or not, she's a real person. She drives her own car, I've bumped into her at CostCo, and so on. And I'm really glad that she is so successful, because her success is the success of the company that puts food on my table, pays my mortgage, etc. I can see that it's her skill, her work, that has built the enterprise, and I'm grateful that she continues to invest those into its success. And for what it's worth, I know that she personally feels the responsibility of the livelihood of a couple of thousand employees on her shoulders.
