Generally I find this rhetoric is popular when people are making decisions for other people rather than those people articulating their desires.
For example, I voted with my feet. I used to live in the US, but I moved (back) to Germany, because despite the fact that I could make tons more in the Bay Area, my standard of living is much higher here.
This obviously doesn't mean that any wealth inequality dominates any absolute level (quick: everyone gets nothing!), and getting the balance right is tricky.
But looking at the world happiness index, it is obvious that European countries are doing a pretty good job.

You can blame capitalism all you like, but this is a fundamental tenet of brain chemistry. No matter how well off we are, our dopamine level adjusts to that.
This isn’t good or bad. It’s just the way humans are.
