I’m sure Quin would argue that he is incentivizing rather than penalizing. Either way, my bigger problem with his proposal is that it is quite a concession to those who want to raise the payroll tax cap or remove it entirely. I understand that what Quin is proposing is far more limited than that, but once you concede that we should have a higher payroll tax cap to ensure progressivity and increase the revenue flow to Social Security, then arguments against more sweeping Democratic proposals come down to a matter of details.
