For a while I have advocated for the idea that we eliminate the corporate income tax and simply tax capital gains and dividends as regular individual income. Corporate profits eventually flow to one or the other. Out would go a whole expensive class of taxation that has all kinds of distorting effects (and really does not raise that much money). Out would go the tax preferences for corporate debt over equity financing. Out would go double taxation of investment income. Out would go the disincentive to repatriate corporate profits and relocate headquarters to foreign countries. And out would go the perceived need for the goofy "Buffett Rule."
At least some on the Left might be open to the idea.
