Hmmm, payroll taxes cap out at about $110,000. Who pays the full amount every time? The rich. Now, should they keep paying more, eliminate the cap?
The question was about the relative percentages paid in taxes. If you change the definition of "taxes" to exclude payroll taxes, then you end up with the misleading results the Tax Foundation reports.
The rich do not pay a higher percentage of their income in taxes than the middle and working class. If you evaluate total incomes instead of adjusted incomes (since the wealthy are able to make far better use of the tax code, which after all, was written for them), then you see that the rich pay a far lower percentage of their incomes - their true incomes - in taxes.
The Tax Foundation is an advocacy group for energy and pharma corporations that don't want to pay taxes. Period. They are as phony as a three dollar bill. And their "reports" are excellent examples of how you can mislead with statistics.
