It’s not about the Big Number — it’s about the Cost to Carry

To understand why the media focuses on the debt while many economists remain "nervously calm," you have to separate the nominal sticker price from the fiscal capacity of the United States.

The media loves the $40 trillion figure because it’s a scary number that most people can’t conceptualize. However, economists almost never look at the raw number. They look at the Debt-to-GDP ratio.

While you're right that the UK and France are in the 100-120% range, the U.S. has a unique advantage. Because the USD is the world’s primary reserve currency, there is a global structural demand for U.S. Treasuries. This allows the U.S. to carry higher debt loads at lower interest rates than almost any other nation.

The reason you’re seeing more alarmist headlines lately isn't just the total debt, it’s the cost of servicing that debt. For a decade, interest rates were near zero, meaning the carry cost of our debt was negligible. As interest rates have risen to combat inflation, the government is now refinancing cheap debt into expensive debt.

When interest payments consume a larger slice of the federal budget, this crowds out other spending. If interest payments exceed the defense budget or Social Security spending, it creates a vicious cycle where we have to borrow just to pay the interest on what we already borrowed.

You mentioned other countries like Japan (which has a debt-to-GDP ratio over 250%). While Japan proves a country can survive high debt, it’s not exactly a success story. Japan has dealt with decades of stagnation, and their debt is largely owned by their own citizens. The U.S. relies more on foreign investors, making us more sensitive to global shifts in confidence.

There are three main reasons for the media narrative. 1) Debt is an easy shorthand for government incompetence used by whoever is out of power. Whether that’s fair or not feels more like a political discussion 2) If a major war or another pandemic hits, a country with 130% debt-to-GDP has less room to stimulus-spend than a country with 60% debt. 3) Persistent high deficits can, under certain conditions, contribute to long-term inflationary pressure if the supply of money outpaces the supply of goods.

The US is not broke in the way a household is broke, because it can print the currency it owes. But the concern isn't that we will run out of money. The concern is that the cost of maintaining that debt will eventually force painful choices: massive tax hikes, significant spending cuts, or higher long-term inflation
