"It is instructive to note that the $2.5 Trillion Social Security Trust Fund has value, not as a tangible economic asset, but because it is a claim on behalf of beneficiaries on the goods and services produced by the working population. This claim will be enforced by the United States Government although the precise monetary mechanism of enforcement is yet to be determined. In order to repay the Trust Fund, the United States government has three options, which may all be pursued to varying degrees."
So 2.5T of the 13.5(?)T federal debt is owned to social security, people worked, they had their money taken from them and they expect to get it back, seems only fair.
for the tax that is the payroll tax. It was basically keeping even this year with ss payouts until they cut the payroll tax. Now it is short. One might think they are trying to kill social security by cutting is tax revenues.
