“It’s not hypocrisy. He said WE should pay more taxes. Ne never said HE should pay more taxes.”
The main reason Warren pays lower taxes is the carried interest loophole and paying the capital gains rate on appreciated assets instead of the high marginal rate.
Democrats want high marginal tax rates in order to keep people from accumulating wealth. As far as those who already have wealth are concerned, Democrats quietly support the loopholes, lower capital gains rate, and tax free treatment of municipal bond interest their billionaire supporters (Warren Buffett and Tom Steyer) take full advantage of. The Senator from Wall Street, Chuck Schumer, is constantly screaming for higher individual tax rates on the middle class while he quietly keeps repeal of carried interest out of tax bills.
The Democrats are aided by the GOPe. They compromised on marginal rates while doing the bidding of their Chamber of Commerce bankers to keep tax simplification, and elimination of preferences, off the table.
