Deficit Scold.

            There are big, important things.  Often they are dull.  There are small, unimportant things.  Often, they grab the headlines.  The big, important things are both “global” (the health of the world economy, climate change, global demography) and “parochial” (the economic situation of the United States, the state of American “hard” power, the current political polarization).  The “big” things are worth thinking about, the “small” things not. 

            One “big” thing is the government deficits and national debt.  Earlier in 2024, the Congressional Budget Office (CBO) projected a 2024 U.S. government budget deficit of $1.6 trillion; in mid-June 2024, it revised that to $1.9 trillion.[1]  Even this is probably over-optimistic.  It includes an assumption that the tax cuts passed in 2017 during the first Trump administration will be allowed to expire in the near future.  Politically, this is a very unreasonable assumption.  President Joe Biden has said that he would extend at least some of the tax cuts and Presidential-candidate Kamala Harris is currently expected to model her basic economic policy on that of the Biden administration.  For his part, Donald Trump has pledged to extend all of the tax cuts.  Fully extending the tax cuts would reduce revenue by $5 trillion over ten years. 

The fundamental problem is an imbalance between spending and revenue.  In recent decades, this has led to large annual deficits.  The deficits have been covered by borrowing.[2]    

What are the sources of these deficits?  First of all, a large aging population has started relying on Social Security and Medicare/Medicaid.[3]  Second, borrowing money requires paying interest.  Even at low interest rates, a quantitatively expanding debt will increase the amount of interest that has to be paid.  The CBO estimates that interest payments will rise from $892 billion in 2024 to $1.7 trillion in 2034.  Higher interest rates, used to control inflation, compound this effect.  At the same time, the United States has spent forty years cutting taxes. 

The national debt of the United States—all the accumulated deficits—stood at about $20 trillion in early 2017.  By mid-2024, it had increased to $35 trillion.[4]  One budget expert judges that “the overall fiscal and economic environment is a lot worse” than before Trump and Biden occupied the White House.[5]  The CBO has recently projected that the U.S. national debt—all the accumulated deficits–would reach or surpass $56 trillion by 2034.  In 1999, the national debt amounted to 99 percent of Gross Domestic Product (GDP); in 2034, it projects that the debt will be 122 percent of GDP.  “[T]he country’s fiscal backdrop is increasingly grim.”[6] 


[1] The Biden administration blames the Republican tax cuts for the deficits and debt.  However, the jump from $1.6 trillion to $1.9 trillion sprang largely from the Biden administration’s cancellation of student debt, from the military aid provided to Ukraine and Israel, and from unexpectedly large payments for Medicaid. 

[2] That is, for decades now, Americans have wanted a bunch of stuff, but they haven’t wanted to pay for it.  Instead of doing without any of the things that they wanted, they borrowed the money in return for I.O.U.s in the form of Treasury bonds.  An I.O.U. is a promise to pay in the future.  It has been a long-running complaint among what the great economist Paul Krugman calls “deficit scolds” that “we are leaving our children a mountain of debt.”  That is true only if our children are willing to pay it.  Such a willingness assumes that they are made of sterner stuff than their predecessors.

Long Term Trends 3.

In 2010 and 2011, New York Times correspondent David Leonhardt turned to the problem of the long-term deficit.[1] In his analysis, that deficit arises from “the world’s highest health costs (by far), the world’s largest military (by far), a Social Security program built when most people died by 70—and to pay for it all, the lowest tax rates in decades.” By Leonhardt’s estimate, we will need about $500 billion a year in annual deficit reduction for the next decade. The money will have to come out of the three big spending categories and from more revenue.

The Medicare budget is the “linchpin of deficit reduction.”  Leonhardt recommended introducing incentives for people to choose cost-effective health-care. In practice, that will mean taxing employer-provided health-care benefits like the income they really are. The cost has risen massively since 1975. This encourages spending on health-care, rather than using the market to restrain price increases. Also, it is a benefit available only to people with employer-provided health-care. So, Americans get taxed differently for no good reason. This cost the government $264 billion in revenue in 2010. The federal tax subsidy created by sheltering them from taxes benefits drug makers, hospitals, and insurers.[2] He also wanted Medicare to refuse to pay for health care that cannot demonstrate that it makes people healthier.

Test social programs for actual effectiveness. Lots of them just exist, rather than achieving anything. Doubtless, many Republicans would say the same thing about the encrustations of regulations on business and industry that have grown up over the decades without ever being sunsetted.

Last, cut military spending by $100 billion a year to reverse the post-9/11 expansion.

Some leading conservatives—Mitch Daniels, Glen Hubbard, Gregory Mankiw–have endorsed means-testing Social Security and Medicare benefits. That is, shove more of the cost of their own care and retirement off on people who can afford to pay it.

Leonhardt also favored higher taxes on the middle and upper classes. The mortgage-interest deduction chiefly benefits people in the higher income brackets. Tax breaks for investors (IRA exclusion, $12.6 billion; lower tax rate for dividends, $31.1 billion; lower tax rate for capital gains, $36.3 billion; not taxing capital gains on items left to people in wills, $39.5 billion; and the 401(k) exclusion, $52.2 billion) total $171.70 billion in ‘lost” revenue.

Social Security and Medicare are essentially about paying for the past. (Often an improvident past.) Spending on education, research, and infrastructure are about paying for the future we desire. Leonhardt argues that we should actually be spending more on the future.

However, it isn’t clear that American democracy has the ability to confront powerful and well-entrenched interest groups. Reforming Medicare would involve taking money away from doctors, insurance companies, hospitals, pharmaceutical companies.  Stabilizing Social Security will involve raising the cap on withholding, so that upper income groups get gored and means-testing benefits at the cost of upper-income groups. Raising the taxes on the upper income groups to sustain benefits for lower income groups invited push-back in the past and will do so again. Cutting defense spending has never been as easy as increasing it, especially in the midst of dangers. The refusal of Democrats to define “fair share” makes rational discussion difficult.

Still, laying out the problems and some possible solutions makes it possible to think about the implications.
