The debate in Congress over the payroll tax-cut extension, which is going down the same route as...pretty much every other debate in Congress this session, has created a sort of political Bizarro World. The proposed legislation wouldn't just extend the payroll tax cut, it would also tackle other funding issues. But the payroll tax-cut is where the action is.
The concern, among a strange axis of conservative Republicans and liberal Democrats, is that extending the tax cut will threaten Social Security. Benefits outpaced revenues in 2010. But as this chart from the New York Times shows, that's not unprecedented — Social Security payments ran above revenues in the 1970s and '80s.
However, since the late 1980s, Social Security has been running a surplus, with the extra money invested in interest-earning Treasury bonds. That funds now stands at $2.6 trillion. The cost of the payroll tax cut? $105 billion.
