According to David Cay Johnston's "Perfectly Legal: The Covert Campaign to Rig Our Tax System to Benefit the Super Rich - and Cheat Everybody Else" the richest do pay 70% of FEDERAL taxes....they DO NOT PAY 70% of all taxes however !
The wealthiest have soooo much hidden wealth, along with corporations, that those on payroll incomes actually pay about as much as the wealthy. Johnston's book shows that when TOTAL taxes, state, federal and local taxes are considered, the US has a FLAT TAX system.
Top fifth paid 19% of all taxes; the poorest fifth paid 18% of all taxes. (from page 94, Chapter 7). In essence, the US's flat tax structure is REGRESSIVE and those being shafted by it know this already. The richest like to play upon the ignorance of the tax system, to their own benefit. Corporate interests, according to Warren Buffett, have no more excuse either
