People are used to this tax break now. How hard will it be to let it expire? One of the hallmarks of the Social Security program has been that it is not welfare. People pay into it and thus earn the payouts when their time comes. A permanent payroll tax holiday would make it at least partially welfare. So, is it going to be permanent? Which president is going to be willing to increase middle class Americans' taxes by $1000 a year? Ever.
