Looking ahead, the numbers do not improve. The deficit is forecast to hit 6.1 percent of GDP in 2035.
The result of these large, persistent, and growing deficits is a large and rapid increase in Federal government debt. “From 2025 to 2035,” the CBO writes:
“... debt swells as increases in mandatory spending and interest costs outpace growth in revenues. Federal debt held by the public rises from 100 percent of GDP this year to 118 percent in 2035, surpassing its previous high of 106 percent of GDP in 1946.”
In 2035, in other words, the Federal government debt will be larger relative to national income than it was at the end of the Second World War, when we had just defeated Nazi Germany and Imperial Japan.
The deficit arises from an imbalance between Federal spending and revenues. The CBO forecasts that “Revenues total $5.2 trillion, or 17.1 percent of GDP, in 2025” and reach “18.3 percent in 2035.” If revenues are forecast to climb as a share of GDP, the forecast deficit must arise from an even greater increase in spending. The CBO writes that “Federal outlays in 2025 total $7.0 trillion, or 23.3 percent of GDP…reaching 24.4 percent of GDP in 2035…” These deficits and higher debt are driven, then, not by deficient revenues—indeed, the CBO notes that “Revenues remain below their 50-year average in 2025 but rise above it thereafter”—but by excessive spending: “Measured as a percentage of GDP, federal outlays in CBO’s projections exceed their 50-year average every year from 2025 to 2035.”
“Net outlays for interest increase as debt mounts. Interest costs exceed outlays for defense from 2025 to 2035 and exceed outlays for nondefense discretionary programs from 2027 to 2035. From 2027 on, interest costs are greater in relation to GDP than at any point since at least 1940 (the first year for which the Office of Management and Budget reports such data).”
And this assumes that the rates on 3-month Treasury bills and 10-year Treasury notes decline from 3.8 percent to 3.1 percent and 4.1 percent to 3.8 percent, respectively, from 2025 to 2030-2035.
Those who suggest that the budget can be balanced simply by cutting military spending are living in a fiscal fantasy, especially in a time of rising global tensions.
This is President Trump’s fiscal inheritance. He cannot feel too aggrieved, however. His first administration saw an increase in the Federal budget deficit from 3.1 percent of GDP in 2016 to 4.6 percent in 2019, before COVID-19 hit.
But we cannot place all the blame on the politicians. To some extent, they are simply giving the American voters what they want. During last year’s presidential campaign, the candidates for President and Vice President debated for a combined total of 270 minutes. At no point were they asked a direct question about the Federal government’s deficits and debt and what they would do about them. This ought to be the biggest issue in American politics and hardly anybody cares.
Whether you’re one of those who believes that the United States should police the world or one of those who believes that it must attend to its own problems first, fixing the explosion of Federal government debt has to be a priority. Just as America grew strong because it had a strong economy, it will grow weak if its economy is allowed to grow weak under the growing weight of debt. Not for nothing did Thomas Jefferson urge Americans to “place economy among the first and most important of republican virtues, and [regard] public debt as the greatest of the dangers to be feared.”
