That's a lesson in misleading statistics. Inequality has risen to absurd levels, and just keeps getting worse. It's not "pretty progressive."

First, you are thinking of people whose main source of wealth are assets, not income.

Also, I don't think inequality is a problem, it's better that than everyone being equal, because as history shows, even then, there are some that are more equal than others, and others are just poor.
