Time and time again it is shown that lowering tax rates increases tax revenue when the tax rates are too high. The problem isn't the income side of the equation - it's the outgo. Until the orgy of spending in congress (BOTH parties) ends, the deficit will continue to soar.
You are 100% correct when you say that the problem is out go not income. Which is also the truth for much of the population in this country.
I know people who’s spending will always outstrip their income no matter how much money comes in.
With the government, printing its own money simply ensures that the gap between income and outgo will indefinitely increase.
