Wrong. Tax rates between 1945-1980 worked just fine. At which time the middleclass was at its peak, and national debt was negligible.
The middleclass has been cut to a fraction of what it was, destroying the traditional family, and the national debt is out if control.
All due to tax cuts for the wealthiest people, and out of control military spending.
What I know as a fact, is those tax cuts and that out of control military spending, are 100% of the problem.
Just as soon as out of control military spending is halted, and tax rates are reinstated to what they were in 1979, both the debt problem, and spending problems go away.
