The rich used to be able to live a different kind of life than the ordinary people. Now they live the same life, but gold-plated with diamonds glued to it.

Instead of worrying about "income inequality", we should focus on pushing consumption equality further down the stack so that even our "poor" largely have it. We still have a long way to go in this respect. I'd say that the 'middle class' still lives a bit of a different kind of life than the 'working poor'. A guy who lives on 10k/year is much farther away from a guy who makes 100k than that guy who makes 100k is from a guy who makes 10mil.
