@rbreich Would there be a way to tax any significant financial action progressively, based on the amount of wealth inequality it creates?
We would need something akin to an advanced sports metric (think Inequality Above Norm as a numerical value, like Wins Above Replacement in baseball). Any stock buyback, corporate merger, massive layoff, predatory interest rate profit, etc. could be plugged into the formula and taxed accordingly.
The more inequality produced, the higher the tax, so as to render certain actions no longer worth it. If a financial action increases equality it would receive a tax credit.
