Public Cash Money
The following is a fictional account. Any resemblance to actual hiring practices at major central banks is purely coincidental and deeply unsettling.
The candidate arrives on time. He has a PhD in economics from a respectable university. He has published several papers in peer-reviewed journals. He has read the data. All of it. This, as we will see, is the problem.
The interviewer is a senior official at the Federal Reserve. He has also read the data. He has chosen, professionally, not to think about it.
The interview begins.
Fed
Thank you for coming. Let’s start with the standard questions. Can you define price stability?
Candidate
Certainly. Price stability means that the purchasing power of the currency remains relatively constant over time. Citizens should be able to plan, save, and invest without worrying that their money will be worth significantly less in the future.
Fed
Excellent. And would you say that the Federal Reserve has achieved price stability since, say, 2000?
Candidate
No. The dollar has lost approximately 87% of its purchasing power since 2000. According to Bureau of Labor Statistics data, what cost $100 in 2000 requires approximately $187 today. That is not price stability. That is a significant and sustained erosion of purchasing power.
Fed
Hmm. Let’s move on. Are you familiar with the r < g framework — the argument that debt is sustainable as long as economic growth exceeds the interest rate on the debt?
Candidate
Yes. It’s an elegant framework with a significant empirical problem. Between 2000 and 2026, US GDP grew from approximately $10 trillion to $27 trillion — an increase of roughly 170%. In the same period, US national debt grew from $6 trillion to $39 trillion — an increase of approximately 550%. The debt grew 3.2 times faster than the economy. The r < g condition was not consistently satisfied, and even when it was, the debt still grew because the framework doesn’t account for the structural deficit that adds new debt each year on top of the interest.
Fed
Those are… interesting numbers. Are you familiar with endogenous growth theory? The work of Paul Romer, for example — demonstrating that technological innovation can drive sustained long-term growth?
Candidate
Yes, I read Romer’s work. It’s mathematically elegant and theoretically coherent within its assumptions. The problem is that it demonstrates the possibility of sustained growth in a model. In the actual economy, between 1944 and 2026, debt grew from a few hundred billion to $39 trillion while the theoretical framework explaining why growth would prevent this was being developed, published, peer-reviewed, and awarded a Nobel Prize. The model worked. The debt grew anyway.
Fed
I see. Let me ask you a direct question. Can you construct a mathematical model demonstrating that economic growth can keep the debt-to-GDP ratio stable or declining over the long term?
Candidate
In a model? Yes. In a model where the growth rate consistently exceeds both the interest rate and the new deficit as a percentage of GDP, the ratio stabilizes. The mathematical condition is achievable on paper. In the actual US economy over the past 80 years, it has not been achieved for any sustained period. The debt-to-GDP ratio in 1944 was approximately 106%. After the most productive economic expansion in human history — the post-war boom, the technology revolution, the information age — it is now approximately 124% and rising. The model can demonstrate the condition. The condition has not occurred.
Fed
But the model is sound, correct? The mathematics of the model are valid?
Candidate
The mathematics of the model are valid. The model’s relationship to the actual monetary system is the problem. In the actual monetary system, every dollar in circulation was borrowed into existence and carries an interest obligation that was never issued alongside it. This means the total debt in the system is always structurally larger than the total money supply. The condition r < g cannot permanently compensate for a system that generates more debt than money by design. It’s like a model demonstrating that a car can be driven on water — valid within the model’s assumptions, not applicable to roads.
Fed
Right. One final question. Robert Lucas — Nobel laureate, one of the most influential macroeconomists of the twentieth century — stated in 2003 that the central problem of depression-prevention had been solved for all practical purposes. Do you agree with that assessment?
Candidate
He said that in 2003. Five years later, the global financial system experienced its worst crisis since the Great Depression, which Lucas had declared solved. I have enormous respect for Lucas’s mathematical contributions. But declaring a problem solved while the structural conditions that produce it remain intact is not analysis. It is optimism. The depression-prevention problem has not been solved. It has been deferred — at the cost of $33 trillion in additional debt since the year Lucas declared it solved.
There is a long pause. The interviewer makes a note. The candidate waits.
Fed
Thank you for your time. We’ll be in touch.
They are not in touch.
Three weeks later, the position is filled by a candidate who answered the question about price stability with “approximately 2% annual inflation, consistent with our mandate,” the question about r < g with “growth-friendly monetary policy can sustain debt trajectories over the medium term,” and the question about Lucas with “a foundational contribution to our understanding of rational expectations.”
He had not looked at the data. This was considered a significant qualification.
He is now a Senior Fellow. He has published four papers this year. The Nobel Committee has him on their watchlist.
A Note on the Mathematics
The numbers cited in the interview above are not fictional. They are verified, sourced, and available to anyone who wishes to check them.
The dollar has lost approximately 87% of its purchasing power since 2000. The US debt has grown from $6 trillion to $39 trillion — 3.2 times faster than GDP — in the same period. Robert Lucas did state in 2003 that the central problem of depression-prevention had been solved. The 2008 financial crisis occurred five years later. Paul Romer did win the Nobel Prize in 2018 for endogenous growth theory, funded by the Sveriges Riksbank.
The interview is fictional. The data is not. The candidate who answered honestly does not work at the Federal Reserve. The candidate who did not look at the data does.
This is, as far as I can determine, not satire.
The model works.
The debt grew anyway.
The problem was solved.
The crisis arrived anyway.
Prices are stable.
The dollar lost 87% anyway.
In the model, 2+2=5.
In the data, 2+2=3.
At the Fed, the model gets the job.
$2+2=4. Period.
