Do much moling, perchance?
There is no trust fund. There is nothing more than a single treasury IOU - printed on real paper even - that cannot be negotiated or sold on the market and that therefore cannot be repaid
except from out of the general tax revenues. Since the government is already running annual trillion, plus dollar deficits, that means that there will have to be additional tax increases (or additional borrowings - but that doesn't change the underlying insolvency issue of the entire government) to pay off this IOU.
Since the government
cannot repay this phony IOU without raising taxes (or borrowing and creating even more debt elsewhere), it follows that it is not logically possible for there to be any sort of a "fund" - trusted or not - in any even half-assed sense to support future Social Security benefits payments.
In other words, there is no trust fund, and Social Security is now insolvent, period.
Since there is NO trust fund, as soon as they go in the red, THEY ARE OUT OF FUNDS.
They can only continue to operate with additional tax dollars.
