How Social Security increases the "deficit", and why it doesn't matter
One of the unfortunate consequences of the public's debt illiteracy is that we use the words "deficit" and "debt" interchangeably, even though they aren't the same thing.
Deficit is an accounting statement of the government's cash flows over a period of time, usually for a fiscal year. Debt is the total amount of money the government owes to its creditors. You might think that the current year's deficit is simply added to the debt, but that is not the case.
Much is being made of the government's fiscal predicament, especially because the national debt just hit $40 trillion for the first time ever. It's quite appropriate to look at what's driving the ever-increasing debt, but unfortunately our very best journalistic enterprises (NPR and the Washington Post, for example) often botch the job. Three years ago NPR's Deirdre Walsh said Social Security and Medicare are the "biggest drivers of the debt." In March of this year the Washington Post's editorial board said "the money retirees receive today is funded by a combination of taxes on workers, who are on average poorer than retirees, and debt." Both statements are false.
Just the other day the Washington Post's editorial board said "Social Security and Medicare both add to annual deficits right now, even though the trust funds still have positive balances on paper," about which I wrote a scathing critique in which, alas, I called the board "stupid." Notice in this rendering the word "deficit," which we'll get to in a moment.
Over the years I've written many times about how Social Security is entirely self-financed through the payroll tax. I've explained why it doesn't increase the debt (also to be discussed shortly) and never has. See, for example, this, this, and this. I have never written about Medicare and am not doing so now. The two programs have very different financial realities and, quite crucially, Medicare's problems are deeply connected to the very high cost of healthcare in the United States, which is an outlier among advanced countries, and which we've never been able to adequately address.
Social Security is different. It has always paid its own way and still does. It has never added a penny to the debt and doesn't today. Thus Social Security isn't a "driver" of the debt at all. Somehow NPR, the Washington Post, and others never figured that out. How can that be?
Frequently in my explanations I've mentioned but perhaps haven't well explained the confusion in the public mind about the words "deficit" and "debt." I'm going to more explicitly clarify the distinction here (but without numbers), so you can understand how you should be thinking about Social Security's contribution to each.
As I said, deficit relates to an accounting statement of the government's cash flows over a period of time, usually for a fiscal year. The simplest way to think about it is that you add up all the government's revenues (ie., from taxes), and add up all the government's expenditures (ie., spending on everything the government buys or does), and subtract expenditures from revenues. If the result is positive you have a surplus. If the result is negative you have a deficit. When the government is running deficits it needs to borrow to make up the difference in order to fund its operations.
The government's debt is literally the sum total of everything it owes to its creditors. Whereas deficit is usually an annual statement of cash flows, debt can accumulate over years and decades. As I said, the government debt just hit $40 trillion. That's the total amount the government owes to all the entities that have loaned it money in various ways over time. If you hold treasury bonds, either through direct purchases or through your retirement accounts, you are one of the government's creditors. You naturally expect the government to eventually pay back the amount you loaned it, and to pay you interest in the meantime. Those are the two relevant features of debt: it needs to be paid back, and the government needs to pay interest on it.
You might think that each year's deficit adds exactly the same amount to the overall debt, but that is not so. Social Security is the best example of why.
Social Security, which has existed since the 1930s, is and has always been entirely self-funded through a dedicated payroll tax ("FICA" on your paycheck stub). The program was originally designed as a pay-as-you-go system, where current workers fund benefit payments to current retirees. But in the 1980s it became clear that when the baby boomers began retiring some decades in the future, the program would collapse because there would not be enough workers to pay the benefits of all those new retirees.
In the 1980s President Reagan impaneled a commission, headed by Alan Greenspan, to address the problem. The solution, which was enacted into law, was to increase the FICA tax rate beyond what was needed to pay current benefits, in order to build a massive trust fund which would help pay Social Security benefits when the baby boomers retired way into the future. This was extremely long term planning, looking out decades in advance.
It worked. Baby boomers have been retiring for quite a while, and current benefits to retirees are now being paid by a combination of current payroll tax receipts and withdrawals from the trust fund, which to this day carries a large positive balance. (But it's being depleted rapidly, and is expected to be entirely used up in several years. A fix is badly needed.)
Notice what this arrangement has done to our conception of budget deficits. By definition and intent, for several decades Social Security was running surpluses to build the trust fund. That means payroll taxes being collected exceeded benefits paid to retirees. Our definition of deficit, above, is revenues minus expenditures. For a considerable time Social Security had revenues well in excess of its expenditures. And here's the thing. When Social Security's revenues and expenditures were added to all the government's other revenues and expenditures, it had the effect of making the overall reported government deficit lower than it would have been if Social Security had been left out of the calculation. For a lot of years Social Security had the effect of masking the size of the federal budget deficit. By the way, Social Security's finances were supposed to be reported separately, but usually they weren't when communicating the size of the deficit to the public.
Now the situation is reversed. Tax revenues—the payroll tax—aren't nearly enough to cover benefit payments to retirees. The trust fund, which was intentionally fortified all those years, makes up the difference. The treasury simply makes withdrawals from the trust fund to pay for the portion of benefits for which current payroll taxes are insufficient.
Which is great. Really. The system is working exactly as designed, and kudos to the Greenspan Commission and the government for successfully planning decades in advance for this eventuality. But notice what the current situation does regarding our conception of deficit. Withdrawals from the trust fund don't count as current revenue. (The original tax receipts that went into the trust fund were revenue when they were collected, and they were accounted for as such long ago, which is why they masked deficits.)
So if we define deficit as a negative result when expenditures are subtracted from revenues, Social Security is running a deficit by that definition. And if we combine Social Security's revenues and expenditures to the government's overall revenues and expenditures, the effect is to increase the size of the government's overall budget deficit beyond what it would otherwise have been. Whereas Social Security masked the size of the deficit for many years, it's now making the deficit look bigger.
And it just doesn't matter! Deficit is not debt. Deficit does not need to be paid back; debt does. Deficit does not require interest payments; debt does. And while Social Security increases the deficit by some increment, it does not increase the debt in the slightest! This is why you should fixate on the debt, not the deficit, and understand the difference.
The reason Social Security doesn't increase the debt is that its apparent "deficit spending," which is an accounting reality, is entirely a function of withdrawals from the trust fund, to make up the current tax (ie., revenue) shortfall. The trust fund contains real assets, intentionally accumulated for that very purpose.
You can surely see intuitively why paying with money you previously collected and set aside doesn't increase the debt, right? But critics such as the Washington Post insist that the government is pulling a fast one. Because the trust fund's assets consist of special issue (non-marketable) government bonds, the critics cry foul. They say that because the money the trust fund loaned the government has been "already spent," the trust fund consists of "worthless IOUs" from the government to itself.
The answer to this is twofold. Please please please work as hard as you need to to resolve this intellectually, by thinking it through until you get it. You'll be glad when you realize it makes sense, because understanding things is always more satisfying than not understanding. The Post was unable or unwilling to do the work, but you should. The links I provide above to my previous writing will help you do so.
But note also as an objective statement of fact that the government's official accounting of the national debt shows that I am correct. (You'll need to do some digging. This explains more about how to do so.)
When the treasury needs to make withdrawals from the trust fund (which is a creditor to the government and duly noted in the government's debt accounts; see the previous paragraph), two offsetting transactions occur. First, the amount the government owes to the trust fund is reduced by the amount of the withdrawal. Government debt in the amount of the withdrawal is thus being retired. But to pay back the trust fund (in order obtain the money to pay Social Security benefits) the government needs to issue new debt, which it does by selling bonds to the public. The new debt increases debt. The new debt and the old, retired debt cancel exactly, and the overall indebtedness of the government remains entirely unchanged! Such offsetting transactions make perfect sense to any accountant, and they should to you too.
That's how it works and how it's always worked. Social Security collects taxes, makes trust fund withdrawals, and pays retiree benefits, all without changing the national debt one iota. Because deficits can be misleading, and because it's debt that actually matters, always concentrate on the debt.
The Washington Post doesn't get it. It said (quoted above) Social Security "add[s] to annual deficits right now," but that just doesn't matter. It has also said (quoted above) that Social Security "is funded by a combination of taxes on workers ... and debt," but that is false.
Contrary to the Post, Social Security isn't funded by debt. It is and always has been funded by its own dedicated revenue stream, the payroll tax, some of which has been accumulated in the trust fund. It has never added a penny to the debt. Because the country will be increasingly wracked by concerns about its growing "debt crisis" going forward, it's crucial, as we consider solutions, to understand what does and doesn't drive the debt. Social Security just doesn't. Never has. So we need to quit implicating it in the problem.
