It's from an article by Robert Reich who is currently a professor of public policy at Berkeley.
The very idea that Social Security might be on the chopping block in order to pay the ransom Republicans are demanding reveals both the cravenness of their demands and the callowness of the opposition to those demands.
In a former life I was a trustee of the Social Security trust fund. So let me set the record straight. Social Security isn’t responsible for the federal deficit. Just the opposite. Until last year Social Security took in more payroll taxes than it paid out in benefits. It lent the surpluses to the rest of the government.
Now that Social Security has started to pay out more than it takes in, Social Security can simply collect what the rest of the government owes it. This will keep it fully solvent for the next 26 years.
