Sorry, I should have been more specific. I've been wary of wealth for so long that I've internalized that feeling, so I forgot to phrase it more like "people are ok with being wealthy while others are poor".
I could never be a billionaire or even a millionaire, and then walk around and not see the countless people suffering all around me, and around the world.
Now, I imagine many of them feel that they are making a positive contribution to the world by employing people, creating products that help people, making charitable donations, etc.
But that stuff stems from the ego. I believe that true wealth is in divine things like the love between a parent and child. Stuff that doesn't cost money.
This isn't just feel-good woo woo stuff. A society could be built around love as surely as it could be built around fear in capitalist societies. Science and technology's greatest failure is that there's still scarcity. A contrived scarcity now, that keeps people working so hard and distracted that they never get a chance to catch a breath and question the system. Just so that a chosen few can suckle on the priceless time of the poor, using them as human chattel.
