As far as the general fund being in deficit, how they resolve that has nothing to do with social security, which has a healthy trust fund to draw upon until 2034, after which benefits will automatically shrink until payroll contributions are enough to fund the trust fund again.

If on the very small chance you are not in favor of cutting social security in any sense, know that the argument that there "is no trust fund" and "it's just IOUs" is a right-wing argument, a right-wing frame, that is typically only advanced to justify cutting social security in some way. If you are not in favor of cutting social security, find different language. If you are, then be intellectually honest about your views that government has no role in doing what social security does, rather than engaging in myths about non-existence of trust funds.
These are two completely separate concepts, but if you insist on equating them, here we go:
Imagine you borrowed money to a business. That business then spent the money and gave you an IOU.
How is the business going to repay you when you want to withdraw? Like I said in my original comment, it will have to:
A) Raise their prices.
B) Cut spending (like employee benefits).
C) Borrow from somewhere else.
So much nonsense here in the rest of you comment. I think the best part is where you claim I have an agenda because I'm being factual, but you keep trying to shift the topic into taxing the rich.
