You forgot your /sarc tag.
Seriously, I find it hard to believe that ANYONE paying ANY attention to the world today still believes in a "Social Security Trust Fund".... What you describe would be AWESOME... but, that's NOT how they do it.
You'd be better off telling us more about Santa Claus.
answers:
‘The Social Security Trust Fund was established in 1939 to receive monies collected for Social Security through payroll taxes. The monies in this fund are managed by the Department of the Treasury; they are not, nor have they ever been, put into the “general operating fund.”
However, the Social Security Act specifies that the monies in the fund may “be invested in securities backed by the full faith and credit of the Federal government,” such as treasury bills, treasury notes, and treasury bonds, as well as special issue bonds. So, essentially, the government can “invest” Social Security funds by lending them to itself, then spending that money on programs not related to Social Security (e.g., defense, foreign aid, education). This has always been the case.
During the Johnson administration, Social Security and other Federal programs that operate through trust funds were counted officially in the budget. This did not mean that it was actually part of the general fund, rather that it was finally recorded as part of the budget.’
THIS is propaganda.
