I would support a zero corporate tax.. PROVIDED.. that we reestablish a truly progressive tax system that includes all individual income, including capital gains (except on primary residence).. with a top marginal rate of 75%.. for incomes over say $1 million.. and that all corporate profits leaving the country were taxed at a 50% rate. This would provide a powerful incentive to reinvest in the country.
Add this to the tariff revenues that would accrue with the rescinding of Free Trade Agreements.. with the intent of supporting full employment and an integrated national industrial economy. With that we likely wouldn't need Sales Taxes which depress demand. We should implement a tax on corporate retained earnings to further the incentive to reinvest.
Essentially its the system we had before the corrupt system of Free Markets, Monetarism (free markets in currency and credit) and Regressive Taxation took over in the early 1970s.
