Congress has been raiding Social Security's "surplus" for decades, instead of investing the money. Congress, the Federal Judicial, and the President, ETC., all are part of a completely different system.
If Congress REALLY wants to "Fix" Social Security, they would either join it or let it join them, instead of running a completely separate system, just for them. If Congress and the President were part of Social Security, they would not let it fail.
Until they join it, they have no REAL interest in saving it. What are they really up to?
