In a recent LinkedIn post, Nathan Crockett, PhD highlights a startling statistic about the U.S. national debt, emphasizing a significant shift in how borrowed funds are allocated. He points out that a substantial portion of new U.S. borrowing is no longer directed towards public services but is instead consumed by the interest payments on existing debt.

Nathan Crockett, PhD writes:

“66 cents of every dollar the US borrows goes toward servicing national debt.”

This observation serves as the crux of his argument that the era of readily available, low-cost borrowing has concluded, and the nation is now facing the repercussions of accumulated debt at a time of higher interest rates.

The End of “Free Money” and the Rise of Debt Servicing

The post details how, for approximately 15 years following the 2008 Great Financial Crisis, the prevailing economic narrative in Washington was that deficits were manageable due to near-zero interest rates. This environment allowed the government to accumulate trillions in debt with minimal cost for servicing that debt. However, as Nathan Crockett, PhD explains, the Federal Reserve’s aggressive interest rate hikes to combat post-pandemic inflation have fundamentally altered this financial landscape.

As Nathan Crockett, PhD notes, refinancing this substantial debt at significantly higher rates has created a fiscal challenge. He elaborates on the implications:

“When you apply that rate hike to a national debt exceeding $34 trillion, the math gets really ugly.”

This mathematical reality, according to Crockett, is leading to a situation where net interest costs are projected by the Congressional Budget Office (CBO) to surpass defense spending. This signifies a critical juncture where the cost of past financial decisions is overshadowing current national security investments.

“Crowding Out” or “Dead Money”?

Nathan Crockett, PhD frames this phenomenon as “crowding out,” but suggests “dead money” might be a more apt description. He argues that every dollar spent on interest payments is a dollar that cannot be allocated to other vital areas.

Impact on Public Investment and Services

According to Nathan Crockett, PhD, these interest payments divert funds away from potential investments in:

  • Tax reductions for working families.
  • Infrastructure revitalization.
  • Research and development in crucial sectors like AI and biotechnology.
  • Improvements in education and healthcare.

He illustrates this point with a personal finance analogy, comparing the U.S. fiscal situation to an individual using a high-interest loan solely to make minimum payments on maxed-out credit cards. This, he argues, represents a cycle of increasing leverage and future obligations without any tangible new acquisition or principal reduction.

“Instead of investing in the future, we’re paying for the past.”

Nathan Crockett, PhD stresses that this is not a partisan issue but a matter of basic arithmetic, with both major political parties contributing to the debt over time. He asserts that ignoring this fiscal trajectory, where a nation borrows at rates higher than its economic growth, is unsustainable and could lead to a currency crisis or forced austerity.

A Call for Fiscal Responsibility

The post concludes with a call for serious discussions on fiscal responsibility, entitlement reform, and revenue generation. Nathan Crockett, PhD warns that delaying action on addressing the “interest trap” will only make the eventual economic correction more severe.
