And the problem with the upper middle class and middle class, and from the developed to the developing, from the perspective of those lower who want your stuff, is solved by redistributing your stuff to their pockets. There can be more than one "problem" that can be solved by redistribution.

The vast majority of the profits from those industries are not going to the ultra-rich either. They mostly go to pension funds and 401k holders.

The focus on the ultra-rich is an obvious political ploy. In every western country with a more socialistic arrangement than another, the taxes on the middle class are inevitably higher. And the salaries for high-skill positions are also depressed to begin with, due to legal/social arrangements that force more egalitarian pay scales. You can't get what you want by just taking the income/wealth/whatever of the tippy-top.
