If you raised it to 90% they wouldn't reinvest most of it; people would just quit at that point. Why bother working?
I wasn't really suggesting that we should raise it to 90%, but the concept is that progressive taxation is better at growing the economy than a flat tax. Frankly, we used to have much higher taxes than we do now and the economy was quite stable back in those days.
Forget studies, charts, and diagrams and let's use common sense. Do you really want the government to have that much of a monopoloy over our lives and what we can and can't do with our money? Besides a conservative can do their own studies to so that it looks like their plans are better. Your studies would turn us into Greece.
...Forget studies and charts? You've lost me.
