Treasury securities are worthless to the government because they are liabilities to the government.
Treasury securities that accrue to others held in trust by anyone, including the government, are most certainly not worthless.
They are worthless to the government because they are liabilities to the government. I don't know how may times this has to be repeated. How many times do you numskulls have to be told that you can't loan money to yourself?
If the government opened an account at a bank in your name, then issued bonds and put them into your account, they wouldn't be worthless. In the case of SS, instead of the account being held at a bank, its held at the Treasury. And instead of issuing bonds, the government issues securities similar to IOUs, which is what a bond is anyway.
There's no account in your name, so those treasuries are worthless to you. They are also worthless to the government because the government issued them. When it comes time to redeem them, the party paying them off will be the government and the party collecting the proceeds will be the government. In other words, the government will be paying money to itself.
You really have to be ******* stupid to believe that the so-called "trust fund" has real money in it.
The liabilities of the SS trust fund are owed to the beneficiaries of the trust. The Treasury owes the SS trusts, and the SS trusts owe the money to the beneficiaries. The liabilities of the Treasury to the SS trusts flow through to you, and you receive the benefits from the payments. You do have an account in your name. It is your SS number. The amount you pay in is credited to your account, your account accrues interest, then when you start collecting SS, the account is debited.
SS is structured like a government bond fund that invests 100% of your money into government bonds. The cash flow of the SS trusts funds are exactly the same as any passive government bond fund run by PIMCO, TCW, Vanguard, etc.
If you open an account at Fidelity and buy a government bond fund every month in your 401k, you buy interests in a Fidelity commingled pool, and then Fidelity lends your money to the government. The government then spends it. The value of your Fidelity government bond fund units goes up when the government pays interest. A picture of your cash flows to the Fidelity government bond fund look like this
You saving: Your money --> Fidelity --> government --> spent
Government: Tax revenues --> interest and principal payments --> Fidelity --> your account
You retiring: Your account --> money to you
SS is similar except it cuts out the middleman and issues nonmarketable obligations, i.e., IOUs, rather than securities. Every month, your taxes are transferred to the government, and the SS trusts credits your account for the amount you put in. It builds up over time, and when you start drawing on SS, your account is drawn down. A picture of your cash flows to SS looks like this
You saving: Your money (SS taxes) --> government --> spent
Government: Tax revenues (SS taxes) --> credits SS tax payments and interest --> your account
You retiring: Your account --> money to you
The cash flows are effectively the same. Both US Treasury bonds and SS liabilities are liabilities of the US government.
The big difference is that if the government cuts SS benefits in the future, they are effectively defaulting on the SS trusts. But the market would probably like this and US Treasury securities market would likely rally, which would be a very different market reaction if the government said it was going to haircut Treasury bonds.
