You can view Social Security accounting two ways: First, you can view it as a separate fund, in which case the Trust Fund surplus of $2.5 trillion is very relevant. Or you can view the issue from the perspective of the entire budget, and ask, “how much of the total is paid for by total incoming revenues?” But what you can’t do is mix the two; you can’t honestly switch between the two accounting perspectives just to make a political point about Social Security.
