There is no SS fund that has cash in it. All money not immediately spent is required by law to be invested in treasury securities, ie, loaned to the general fund. And since SS didn't start losing money until just recently, any money "put into the fund" as you wished, would have been immediately pumped back into the general fund and become yet another debt to be paid from future budgets. Your complaint is based on nonsense.It would have kept working except for the increase in life span, the decrease in birth rate, and a few other conditions.
Or maybe they could have actually invested the surpluses instead of using it to prop up the general fund.
Crazy ideas, I know.
Cheney/Bush had the opportunity to put the surplus into the Social Security fund but no, instead they decided to send us all those nifty $300 checks.
What a guy!
