IMO the underlying problem to solve is mobilisng this capacity. And the $$ to do so needn't come from rich people. The US anyway has been running budget deficit, there's also this ~$2T infrastructure bill. Some of that money could be used to solve housing/health/education problems and as an added benefit it'll provide jobs to the US citizens. I'm sure this will have 2nd order adverse effects but they I guess they won't be as disruptive.

I am not saying inequality is a problem; but taxing rich doesn't seem to solve it. It will lead to endless debate and lost time. It will take the focus away from the underling problems which is rotting basic human needs -- food/health/housing/education. The government should address underlying causes that lead to inequality and spend on infrastructure in a big way.
