Whether the federal govrnment is spending general revenues wisely or not, is irrelevant to the whole SS-fund-as-bonds argument.
the analogy I like is, “is the federal government borrowing money to buy a house (investment) or borrowing moeny to buy groceries?” Building roads, bridges, air traffic control systems, subways in big cities - all these add value to the economy that has very long term value, long after the money is spent. Financing education? you are straying into debate territory, simple answer is it depends. Borrowing to pay welfare? Recipe for disaster.
Sorry if this is straying into GD territory, but the probelm is this - it is a good idea for the government to deficit-spend during bad times to prop up the economy, but this Keynseyan doctrine has been re-interpreted by politicos that they have a license to spend, and the occasional surplus (like Bill Clinton’s) seem to be more an accident of good times than government policy.
As the saying goes, “if things can’t keep going on like this… they won’t”.
So the current arrangement is a simple one - the SS fund is a separate entity/pocket/account/whatever. As long as the government reliably pays back its loans, those bonds are good and SS has nothing to worry about except demographics.
however, the feds are quick to add spending and slow to stop it. SS has become as much a welfare payout for the poor and disabled as it is a real pension plan and politicians with a 4-year time frame (or 2 years) are happy to buy votes and let someone else deal with the consequences 10 years later.
but the problem is a different one - SS is the least of the problems, since all the money the government borrows goes into other spending. The SS fund is just the enabler, making it far easier for the government to borrow.
over time 2 things will happen:
-the pool of easy funds will stop being avilable as demographics change.
-the government will either have to spend responsibly, or use inflation to reduce the cost of past debt.
the chance that the government changes the rules is always there. Reducing payouts is politically difficult but can be done; I’m sure with the right incentives, the states will agree to a constitutional change too (we’ll give you the right to cancel your debt…).
(The first step to reducing debt is clawback from people making progressively lesser decent incomes. Once the SS payout is irrelevant to the middle class, they don’t care what the government does with it.)
however, all that is irrelevant to the discussion at hand.
the simple answer is this:
-if you account for the Social Security fund as a separate entity, then the bonds are meaningful.
-if you are talking “total for all govenrment spending” then the bond as asset and liability cancel each other out, yes.
-government spending outside SS is counted as a separate entity - and that entity would have the same issues whether they borrowed from the SS fund or the Chinese. The difference is the fund is a much more friendly and easily manipulated lender if it come to the crunch.
