Well, with that nonsensical argument, everything other than the money in your hands is gone. Gee, I hope you don’t put money in a bank. There is an accounting somewhere, sufficient to issue an IOU, as there is to send you a bank statement once a month. Sure it is not in a “Social Security fund” per se because that money has been subsumed into the general fund.
On another point, however, the SS was setup such that even though peeps may have input 100K$, actuarially, they likely will not get it all out. So the statements put forth here of getting out what was put in is also nonsense.
Yes, there is a Social Security "trust fund". You may not have any faith in it, but it exists.
It's a stack of special US Treasury bonds in a file cabinet in some government office (in West Virginia). Seriously.
Those Treasury bonds are supposed to be the same as every other Treasury bond that has been sold by the government (and the proceeds spent). Those same bonds are held by pension plans, investors, and even governments.
