#JohnHussman suggests essentially an excess margins tax. https://www.hussmanfunds.com/comment/mc260426/
Text: In my view, a more reasonable corporate tax structure would be to apply corporate taxes to gross value added (revenues less intermediate inputs) minus a generous normal return allowance (r x Capital Base) on the company’s stock of real investment and R&D, minus an allowance for labor compensation (up to some fixed amount like $150,000 per employee). It’s simple math, but in this way, you incentivize real investment, R&D, and employment, but you tax the surplus “dominance rents.”
