I still don't get it. The SSTF has been redeeming Treasuries for decades and paying out the monies as benefits. The money going in is "real", and the money coming out is "real", just as with an annuity.
And I think it also real that when the SSTF runs dry, SS payments will have to be cut to about 75%, UNLESS Congress does something. Maybe it doesn't matter and is just linguistics.
The SSTF is "real" but it's not "meaningful".
Think about it this way.
My wife and I split up some of our household bills/payments. One that is very seasonal, and seems to be in a secular increase due to rising costs generally here in CA over time, is electrical. It can be $100 in the dead of winter and $400+ in the summer due to AC, and it seems to get worse every year.
So let's say that my wife contributes in our household for the electrical bill. She doesn't like that lumpy cost when it gets crazy expensive in the summer, so let's say that instead of paying the actual amount every month, she'll just give me $150/month for electrical and anything that isn't used goes into the Household Electrical Trust Fund (HETF). That way when the bill is below $150, we've got growing assets, that we can use to draw on during those few super hot summer months when we're running the AC a bunch.
Well, it would be silly for us to just put that money in a savings account or under a mattress, right? It should probably be in an interest-bearing account! So I offer her a deal... I'll sell her Brad's Bonds that will be held in the HETF and not only will I pay them back when needed, they'll be earning 5% interest. I'm such a swell guy!
And so, every month that she gives me more than the electric bill costs, I give her a Brad's Bond for the difference.
I then take the money she gave me and spend it on beer. It's gone. Because I'm a profligate spender and can't let it sit in my pocket, much like our federal government.
And since that money is already spent, when we get to summer months and I need to redeem those Brad's Bonds to her,
I use cash advances from my credit card to come up with the money. Because where else am I going to get it? I didn't get a second job.
So this keeps going. And every year when the payments from her are larger than the bill, I only apply as much of that excess as I need to pay the minimum payment on the credit card, not to draw down the balance, and spend the rest on beer. So my credit card balance just keeps growing and growing, but from her perspective everything is "fine" because as far as she can see, I keep redeeming the Brad's Bonds.
In this case, our HETF would absolutely be real, but would you say that this was prudent financial planning? Would you say that our household finances are in good shape? Would you say that each time she needs to draw down the HETF and redeem a Brad's Bond, she should be happy about it because although she's getting paid 5% interest, the money is coming from a credit card that "we" as a household will eventually need to pay off at much higher interest?
That's the SSTF. Yes, it's real. It's a real tool that serves to obfuscate the problem and make Americans think that the problem isn't a big deal until the day the SSTF runs out.
