The 2037 date is bogus. SS is a pay as you go system. Once SS goes permanently in the red in 2016, i.e., beneftis exceed revenue, the shortfall must be made up by the General Fund thru the redemption of the non-market T-bills in the SSTF, which is an unfunded liability and the reason why the SSTF is included in the national debt under Intragovernmental Holdings.
Then along came Johnson and a Democrat controlled Congress. The trust fund was disbanded and the funds moved into the General Budget. Then it was Katy-Bar-the-Door. The built up funds were gone through like a dose of salts through a cow.
And, ever since the Seventies they have used the surpluses generated by SS deductions from payrolls to apply to the deficit cause by the over spending.
Give us back the IOU's and then we will see what the system looks like then.
