ding ding ding NEVER. Well actually, http://www.fiscal.treasury.gov/fsrep...mt/mts0914.pdf
for FY 09/30/14, receipts were $3.02 trillion. 3 big items:
Individual income taxes 46%
Payroll (social sec, medicare, retirement withholding on paychecks & employer contribs) 34%
Corporation income taxes <11%
It's going to be a miracle making corporations pay. Republicans want corps to pay even less, while democrats want individuals to pay more. Guess who's on the winning end in both scenarios lol. It is almost a disincentive to earn more to pay more taxes, because the gov will just waste it some more. Government spending is a rabbit hole that no amount of tax revenue will ever fill.
ETA: Going a bit farther, the entire legislature system is broken because Congressmen have zero incentive to pay off the debt ($18 trillion as of last week, with at *minimum* half a trillion each year being added to it with no end in sight) because it does nothing tangential nor immediate for their constituents who elect them. Hah, can you see a senate or rep candidate on a platform of "I pledge to pay $500 billion to the chinese to pay off our debt!" Hell no. They're going to run on a platform of bringing bridge repairs for their district (adds to the debt) or promising to keep their medicare intact (adds to the debt). Zero political incentive to pay off the principal of the debt, lots of incentive to add to it.
