Forty trillion, and nobody signed for it

The number is around forty trillion dollars, and that is the least interesting thing about it. Forty trillion is not a quantity a person can hold; it is a word that means *large*. What can be held is the shape of the line, and the line has a shape because people chose things.

Start with the fact almost nobody believes on first hearing: on 1 January 1835 the debt of the United States was $33,733.05. Not thousands of millions — thirty-three thousand dollars, which was already a modest sum then. The Treasury's own historical table records it, and it is the only figure of its kind in two hundred and thirty-six years. Andrew Jackson had run surpluses off tariff receipts and western land sales for six years to get there, and he treated the debt as something close to a personal moral failing. It lasted about eighteen months. The land boom broke, the Panic of 1837 arrived, and the country has owed money continuously ever since.

That episode is worth keeping because it settles two arguments at once. It is possible to pay the thing off — so the debt is not a law of physics. And paying it off had costs, in a deliberate revenue squeeze and in the destruction of the national bank, which is why nobody has repeated the trick. Both halves are true. Most debt commentary picks one.

The debt was founded on purpose. Hamilton's Report on Public Credit in January 1790 argued that the new government should pay the Revolution's debts at face value and assume the states' war debts too, and the Funding Act carried it in August as part of the bargain that put the capital on the Potomac. The country began owing about $71 million, and the debt was the point: a funded, payable obligation gave the United States credit in Amsterdam and gave every bondholder a personal stake in the union surviving. Nobody who complains that the founders would be appalled has read the founders on this.

The line is mostly wars, and then it is mostly not. Run your eye along the trace and the first hundred and fifty years are a series of spikes — 1812, the Civil War, the two world wars — each followed by a long flat stretch or an outright decline. Debt went up to fight and came down afterwards, because the emergency ended and the taxes did not immediately. That pattern breaks somewhere around 1970. After the gold window closed in August 1971 there was no external limit at all, and after 1982 the peacetime line never seriously turns down again.

Two mechanisms in the register do the opposite of what their names suggest. The debt ceiling was created by the Second Liberty Bond Act of 1917 to make borrowing *easier* — Congress had previously authorised each bond issue individually, and an aggregate cap handed Treasury flexibility it did not have. It became a hostage device only much later. And Gramm-Rudman-Hollings, the 1985 law that promised automatic cuts if deficit targets were missed, was attached to a bill raising the debt limit. Congress has a long habit of legislating restraint and borrowing in the same sentence.

The one stretch that genuinely worked was boring and bipartisan. George H. W. Bush broke a campaign promise at Andrews Air Force Base in 1990 and signed caps and pay-as-you-go rules that made new spending pay for itself. Clinton's 1993 reconciliation raised top rates. Gingrich's Congress and the White House cut a balanced-budget deal in 1997 with a strong expansion running underneath it. The result was four consecutive surpluses, 1998 through 2001. Note what that took: two parties, three separate laws, a decade, and a boom. It also cost the president who started it his job.

What ended it was not an emergency. The 2001 and 2003 tax cuts were legislated against a projected surplus that had not yet arrived, the budget caps expired in 2002 and were not renewed, and two wars were funded through supplemental appropriations outside the ordinary process. Then 2008 arrived, and the register runs from $10.0 trillion to $13.6 trillion in two years — most of which was not the bank rescue at all but the recession removing the tax base underneath it.

The modern pattern is the one worth arguing about, and it is not partisan. The Tax Cuts and Jobs Act was scored by CBO and the Joint Committee on Taxation at $1.455 trillion over ten years and passed at four per cent unemployment. The CARES Act, scored at about $1.7 trillion, passed almost unanimously in a genuine emergency. The American Rescue Plan added $1.9 trillion on a party-line vote after the recovery was visibly underway. Public Law 119-21 in July 2025 was put at roughly $4.1 trillion over ten years once higher borrowing costs are counted — the first bill of that size where the interest line itself was the headline. Four laws, three administrations, both parties, and one shared assumption: that the bill goes to a future Congress.

Interest is the part that has stopped being theoretical. For thirty years, borrowing was close to free in real terms, and a debate about the debt was really a debate about the future. It is not any more. When the government refinances a trillion dollars of short paper at five per cent instead of one, the extra fifty billion is not a projection; it appears in this year's outlays, ahead of everything discretionary, and it is not subject to a vote.

That is the honest case for caring, and it does not require anyone to pretend the number is a moral scandal. Debt is a tool. The United States used it to fund a revolution, hold a union together, win two world wars, and keep several million households solvent through a pandemic. What has changed is that it is now being used at full employment, in peacetime, by both parties, to avoid choosing — and the cost of that avoidance has an interest rate attached.

The plate above marks sixteen of those choices. Every one of them has names on it. That is not an accusation; it is the reason the line can be changed.

The next room does the other half of the job. It reconciles a single fiscal year to the dollar: the debt at the start, every function of spending that pushed it up, every source of revenue that pulled it back down, and the residual the deficit does not explain — readable in total, per person, per household, per person per day, or per second.
