One of the reasons given for why the Social Security trust fund is a myth (even as they say we need to make that mythical trust fund solvent until infinity and beyond) is that the Treasury Bonds in the trust fund are somehow different than normal T-Bills because, by law, they can't be traded.
Well, boys and girls, can we think of another well-known financial asset marketed by the U.S. Government which can't be traded?
Personal Savings Bonds. I guess they're just "bits of paper" or "meaningless IOUs" or whatever.
