Interesting theory. See previous post about the Clinton years. "High" taxes, at the same time as the longest growth period in productivity in our nation's history.
Therefore, "high" taxes do not stifle productivity. At least in the ranges Americans have ever paid them.
We kind of had a LOT of growth and productivity and innovation during the 50s also. Know what the top marginal tax rate was then?????
That might make sense if tax rates were the only thing that had an effect on the economy.
I'm not in agreement with anyone getting tax cuts right now. I just saw that 51% of Americans believe that Obama's plan is to raise taxes on the middle and lower class, when in fact he's saying just the opposite.
