The greatest trick the rich ever pulled was making us believe they pay all the taxes
Payroll taxes are a much bigger hit on the poor than income taxes. So all this whining about lowering income taxes does is force the tax burden to increase for payroll taxes.
(not to mention the disproportionate impact of sales taxes)
And the fact that you can use deductions to reduce your income tax, but there is nothing you can do about payroll taxes only exacerbates the problem.
We need to reduce the payroll tax and increase income tax (not to mention remove the upper limit on Social Security withholding). Not like that will happen any time soon in the current political climate.
