The government borrowing from SS is no different than them borrowing from the Chinese, either way it has to be repaid. I'd like to offer you an annuity. Here's how it works: you give me about 15% of your paycheck every year, and I spend the money on whatever I feel like. I replace it with a piece of paper that says "Dear Byrneseyeview: Please tender to the bearer -- Byrneseyeview -- an amount equal to the sum borrowe…
Here's 2 scenarios. a) Government borrows $4 trillion from the Chinese at 2% annually. b) Government borrows $4 trillion from Americans, by way of Social Security, at 2% annually. What's the difference in what the government owes after 10 years? Either way the government has to raise $4 trillion (plus interest) in taxes, borrow it, or print it to pay it off. Either way everyone is in the exact same boat, except in bo…
Social security is only as "sound" as the will of future taxpayers to pay the inevitably increased taxes required to keep it going, regardless of whether the money is borrowed, promised, set-aside, appropriated, recommended, etc.
Since its inception, social security benefits have been cut little by little to the point where middle class people must significantly supplement it with their own private investments to avoid poverty in retirement.
So there still may be something called "social security" in 20 or 30 or 50 years, but chances are it will bear little similarity to the program's initial inception or even to the program people think of it as today.
You also argue that the government should borrow money. Why not just tax today for what we spend today? Had we done that, Bush would never have been able to go to war in Iraq, the "trust fund" would not be in danger, etc.
Not to digress, however. The biggest threat to social security is that congress won't have the will to use the limited available tax revenue for the program, and the public won't want the drastically increased taxes.
Obama wisely suggested switching SS over to be a welfare program and funding it from general revenue, but the initial concept was that it's not welfare and so nobody should feel like they are on welfare when they receive their social security check. This is a fairly significant matter.
