> Lastly, it seems that Government revenue for Federal and State/Local has actually increased pretty linearly with the population. Despite all the different changes in the income tax rate/other progressive taxes. This supports an overhaul to the tax code to a more simple, flat tax system. From another data source outside this report, I'd have to find it, but historically, no matter the top bracket tax rate, the Federal government collects about 15-17 % income tax. Including when the top rate was 90%+.
This seems like a pretty poor argument for a flat tax and in fact could be seen as an argument against it. If raising top end bracket taxes didn't increase overall income, then it must be the case that it reduced the tax burden on lower incomes -- which is the entire point of progressive taxes. So progressive taxes work, let's keep them!
I view this as mostly orthogonal to the issue of tax simplification, however, which I think is probably a good idea.
