Loosely, I think corporations should have a progressive income tax based on net income (defined in such a way as to prevent Hollywood-style games) or maybe market cap, to disincentivize getting huge and to encourage divestment. Dividends, I believe, usually already have a nominally lower tax rate than capital gains, but the fundamental problem is related to compounding. I therefore think the capital gains rate should be much, much higher and the dividends rate probably somewhat lower.
