Suppose that payments into the system were not spent immediately but used to buy government issued securities that do pay interest, and payments out of the system were made by redeeming those securities. To account for the fact that more will be paid out in the future than is being paid in now, the interest rate would have to assumed greater than zero. This system would work just as our SS system does now, so far as amounts paid in and out go, but it would be slightly less efficient, because of the accounting work in buying and selling, possibly even printing, the securities. Since the effect is the same, if it's pleasing to think of the SS being funded through interest bearing securities, why not think of it that way? Thus, SS does, in effect, benefit from compound interest.
To me, the "Suppose that payments ...." scenario is not the same as " just as our SS system does now".
From it's inception, most of the taxes collected by SS were paid as benefits very soon after they were collected. The small difference was kind of like the balance in my checking account - just enough so my checks don't bounce, but not enough to provide any meaningful long term interest.
I guess I don't know how to figure out the dollar amount on those government issued securities in the "Suppose that the payments ..." scenario. Maybe you could clarify that.
The reasons we get interest on corporate bonds is that we're willing to consume less than we earn. The consumer goods we don't buy are instead being consumed by people who produce capital goods for the corporation that borrows my money. The return of my principal plus interest comes from the productivity created by those capital goods. I see that as a fundamentally different economic process than the IRR in a paygo pension system, so I look for different words to describe them.
