The neo-conservatives report on income taxes:
What changes here isn’t the solvency of the trust fund. What changes is where the money comes from. Payroll taxes mainly come from the middle and working classes. The general fund is supported by income taxes, which mainly come from the well-off and the rich. So, generally speaking, a payroll tax cut that’s compensated for by transfers from the general fund reduces the taxes of the middle and working classes and raises the taxes of the well-off and the rich.
Oh, wait, that’s from Mother Jones.
