So while increasing the tax rate for the upper class will not result in more tax revenues, it should result in a larger percentage of total tax revenue being paid by the upper class - if my simple numbers are correct.
Not necessarily. What happens in practice when the highest marginal income tax rates get too high (are deemed unfair or confiscatory by taxpayers in the highest brackets) is that we find a lot more income deferring, underreporting of income, and a shifting of activities to non-income tax producing activities, and even to those that intentionally generate losses (tax shelters). These are all perverse economic effects which can harm the overall economy in unexpected ways and which do nothing to contribute to healthy economic activity.
The 1970s saw a huge explosion in the proliferation of tax shelters, some legitimate in the sense that they were legal, and some fraudulent. It was very unhealthy for citizens participating in them and for the government to have such activity be so rampant. It funneled capital away from productive activities and diverted government enforcement efforts into investigating questionable practices that its own policies in effect created. Tax shelter abuse was the prime impetus for the broad, sweeping changes to the tax code in the Tax Reform Act of 1986.
Tax shelters have not been eliminated, but their widespread abuse has been curtailed substantially. We have all benefitted from that.
Which leads me to my next question: since GDP seems to grow regardless of the tax rate, what proof do we have that lowering taxes spurns the economy? Ideally it makes perfect sense, but I don't see any numbers to verify it.
I don't know. I don't even know if that supposition is in fact true. Personally, I suspect natural business cycles and major events such as WWII have a much greater impact on GDP than does tax policy alone.
Don't forget that fiscal and monetary policies play a role too. The loosening or tightening of credit induces or inhibits a lot of economic activity. Alan Greenspan isn't revered so highly for nothing.
Thanks again for taking the time with the info and links; it's much appreciated.
You're welcome. I enjoyed discussing it with you and looking up that information. Thanks for asking so nicely.
