So, when the trustees say that Social Security can pay 75% of the benefits, what they mean is that there are enough IOUs in the trust fund to pay 75% of the benefits. But when we start redeeming the IOUs, we will quickly discover that the money isn't in existence. We are going to have to raise taxes or cut spending or otherwise get the money from somewhere else. The trust fund is just a very very clever way of obfuscating the fact that the government has no money saved at all for Social Security.
> But when we start redeeming the IOUs
You are aware, I'm sure, that said IOUs have been redeemed every year of SS's existence.
So if you are saving a lot it could, ironically, be a self fulfilling prophecy that you get no social security.
