Treasury Secretary Scott Bessent has found another opportunity to lecture Senator Elizabeth Warren on elementary economics. In a combative post on X, he accuses Warren of manipulating inflation statistics, ignoring improvements in real wages under President Donald Trump, and selectively choosing figures that make the administration look bad. His language is colorful, his confidence impressive, and his enthusiasm for political point-scoring unmistakable. But there is something rather more important missing from this exchange: the rapidly growing cost of servicing America’s national debt, a problem that threatens to overwhelm whatever progress either political party claims to have made on inflation.
Another day, another Econ 101 lesson for Professor Warren.

Bessent’s argument is not entirely without substance. Inflation accelerated dramatically during the Biden administration, eroding household purchasing power, and lower inflation combined with rising nominal wages can produce real improvements in living standards. His October economic tracker reports annualized core inflation of 2.5% under Trump, compared with 4.7% under Biden, alongside a 1.5% cumulative increase in real weekly wages. Warren, meanwhile, emphasizes the continuing burden of higher prices on households. These figures describe different aspects of the economy, and neither set tells the entire story. Slower inflation does not reverse previous price increases, just as rising average real wages do not guarantee that every household is better off.
The problem is that Bessent’s preferred economic scoreboard concentrates on consumer prices, wages and selected measures of affordability while leaving the federal government’s deteriorating balance sheet largely outside the discussion. This is a particularly striking omission from the Secretary of the Treasury, whose department must finance the debt and manage the government’s borrowing requirements. An administration can celebrate improvements in inflation and employment, but those achievements do not eliminate the consequences of persistent trillion-dollar deficits.
The Congressional Budget Office estimated on October 8 that the federal deficit reached approximately $2 trillion in fiscal year 2026, an increase of $218 billion over the previous year. Government revenues increased, but spending grew faster. The CBO’s longer-term projections put annual net interest expenses above $1 trillion in 2026, rising toward $2.1 trillion by 2036 under its baseline assumptions. That is money spent servicing past borrowing rather than financing new infrastructure, scientific research, public services or tax relief. And it is not some remote problem waiting for a future generation. The fiscal pressure is already visible in the federal accounts.
The arithmetic becomes especially uncomfortable when interest rates remain elevated. Washington must continually refinance maturing Treasury securities, and the cost of doing so depends on the rates investors demand. A recent CBO analysis examined a scenario in which interest rates average 1.5 percentage points above its baseline over the coming decade. Under that scenario, cumulative deficits would increase by approximately $6 trillion. The mechanism is straightforward: higher rates increase interest costs, larger deficits require more borrowing, and additional borrowing creates further interest obligations. It is a feedback loop that deserves considerably more attention than another exchange of insults about economic literacy.
None of this means that the United States is about to run out of dollars or that a debt default is inevitable. The federal government borrows in its own currency and benefits from unusually deep Treasury markets. But those advantages are not a license for limitless borrowing. Debt service can become fiscally unsustainable long before a literal inability to pay: it can crowd out other priorities, demand painful tax or spending choices, and leave policymakers with less room to respond to a recession or national emergency.
Nor is this a problem that can be assigned exclusively to Biden or Trump. Both parties have supported policies that increase deficits, and the debt burden reflects decisions made over many administrations. That is precisely why a Treasury Secretary should be explaining the government’s financing strategy rather than reducing the economic debate to a contest over which politician can assemble the more flattering inflation chart.
Americans are entitled to ask whether wages are keeping pace with prices. They are equally entitled to ask how Washington intends to pay the interest on a growing mountain of debt. Bessent has plenty to say about Warren’s inflation tracker. What remains unanswered is the larger question: how long can federal interest costs continue to rise faster than the government’s capacity to absorb them, and what concrete policy will change that trajectory?
