The $39 Trillion Habit That Washington Cannot Qui

There is a school of thought — serious, not fringe — that holds the national debt is a symptom, not the disease. The disease, in this view, is too much tax revenue, which enables both the spending and the borrowing. On this account, the entitlement state did not produce the debt; abundant revenue made the entitlement state possible in the first place. Curb the revenue and you curb the appetite. The debt follows. It is a provocative argument, and it has the virtue of pointing upstream of where most fiscal commentary stops. My argument today runs alongside it, not against it. Whatever the root cause, the arithmetic downstream is the same, and compound interest does not wait for the philosophical debate to be resolved.

The national debt crossed $39 trillion in March 2026, adding roughly $7.2 billion per day. Interest expense now exceeds $1 trillion annually — surpassing both the defense budget and Medicaid individually, and ranking third among all federal expenditure categories behind only Social Security and Medicare. The CBO projects debt held by the public rising from 101% to 120% of GDP by 2036, with cumulative deficits of $23.1 trillion over the decade. Every American household carries an implied share of approximately $288,000 and rising, borrowed without consent to fund programs many will never use.

The structural driver of the spending side is entitlement growth that neither party has shown the courage to reform. Social Security outlays grow from $1.6 trillion to $2.7 trillion by 2036; health care programs from $1.9 trillion to $3.1 trillion. Mandatory spending, entitlements plus interest, already consume more than two-thirds of federal outlays. Discretionary cuts, including DOGE’s genuine efficiency push, cannot close this gap. Analysts estimate DOGE’s savings in the range of $1.4 billion to $7 billion, less than half of 1% of the annual deficit. That’s not waste disposal. That’s rearranging deck chairs. Whether those programs exist because revenue made them possible, or because the political class manufactured the revenue demand to sustain them, the obligations are real either way.
