The Department of Numbers has an interesting set of charts looking at Tax Revenue as a Fraction of GDP.
You should go to Dept of #s to read the commentary explaining the hows and whys, but meanwhile, see these charts — I added a (ballpark) mean to both series:
Total US Tax Revenue as a Percentage of GDP (~16.5%)
US Tax Revenue as a Fraction of GDP by Component
(Corporate Tax falls from >4% to ~2%)
Please use the comments to demonstrate your own ignorance, unfamiliarity with empirical data and lack of respect for scientific knowledge. Be sure to create straw men and argue against things I have neither said nor implied. If you could repeat previously discredited memes or steer the conversation into irrelevant, off topic discussions, it would be appreciated. Lastly, kindly forgo all civility in your discourse . . . you are, after all, anonymous.
