RedCedar,
Congratulations on undertaking a vital, and oft neglected, calculation. I think most people would be rather shocked to calculate exactly how much money they spent each year on taxes, and that if a check had to actually be written for said amount our government would be forced to be far more fiscally responsible.
I would encourage all those responding to this question to do a further calculation...ask yourself what you got for your taxes, and whether or not it was worth it.
For myself, it works out to a little less than I would have imagined just given the tax rates...a little over 20%.
And do you think percentage-wise that the rate is higher for a specific class?Of course it is...our tax rates specifically enforce this. Almost our entire tax system is based on the concept of progressive taxation, which indicates that people of higher incomes should pay higher rates. However, there is also validity to Jobius' remarks below, where a variety of regressive taxes (gas, liquor, cigaretts, etc.) make the overall tax burden in the US flatter.
Here is a link to the 2006 Federal Tax Rates. The tax tables simply reflect these calculations for various given amounts (I guess a tacit admission that our school system fails miserably in teaching basic mathematics?).
