If they did that, then Congress would have had to borrow money or reduce expenditures in the General Fund. Our national debt would have increased much more and the funds required to service the debt would have taken more of the federal tax dollar. It is a little late now to change things. SS will stop running a surplus in 2018.
How Does the National Debt Affect Me?
SS is a Ponzi Scheme. There were over 40 workers for every retiree in 1937, 16 in 1950, 3.3 today, and 2 in 2030. Unless something is done about our entitlement programs, our children and grandchildren will be taxed to death to pay for our retirement. Those on SS now or soon to retire will collect much more than they ever contributed. That won't be the case for those who follow.
