Rising Income Risk at the Top -- by J. Carter Braxton, Kyle F. Herkenhoff, Chengdai Huang, Michael Nattinger, Jonathan L. Rothbaum, Lawrence D.W. Schmidt

TEXT START: We document an increase in U.S. income risk from 1969 to 2019 using newly digitized IRS tax returns, distinguishing permanent from transitory risk.

The Dissection

The paper quantifies instability inside the existing wage-income regime. Its central move is to show that income risk has spread upward, hit the top 5% hardest, and induced richer households to save more. The result is presented as a macro-financial mechanism: greater insecurity at the top lowers the risk-free rate, widens wealth inequality, and produces a “savings glut of the rich.”

Under the Discontinuity Thesis, this is a measurement of pre-collapse turbulence, not an account of the terminal break. It studies how labor-derived income becomes less reliable while assuming the labor-income system remains the organizing structure.

The Core Fallacy

The core error is a category mistake: confusing greater volatility within the employment system with the destruction of the employment system.

The paper tracks income risk. The DT concerns productive necessity. Once AI achieves durable superiority across cognitive work, the decisive question is not whether high earners face larger shocks. It is whether their labor remains necessary, and whether they own or control the productive AI capital replacing it.

A top earner suffering a negative income shock today is still participating in the wage circuit. A displaced worker in the AI regime may not be. The paper’s risk-free-rate and savings results are therefore second-order effects. They describe capital accumulating defensively while the underlying labor-to-consumption circuit deteriorates.

Hidden Assumptions

• That income, employment, and productive participation remain broadly coupled.
• That rising savings can be interpreted within a stable financial system rather than as defensive positioning before labor displacement.
• That the top 5% constitute a durable economic elite, rather than a mixed group of asset owners, highly paid employees, and vulnerable professionals.
• That historical income risk from 1969–2019 provides a sufficient guide to an AI-driven regime change.
• That redistribution or financial adjustment could manage the problem without confronting ownership and control of productive capital.
• That increased wealth inequality is an outcome to explain, rather than a mechanism determining who becomes a Sovereign and who becomes a Servitor.

Social Function

Classification: partial truth and elite self-exoneration.

The paper supplies a real diagnostic: even high earners are not financially invulnerable, and income instability encourages precautionary accumulation that worsens inequality. But by treating the issue as risk, savings, and interest rates, it keeps attention inside the existing economic grammar. It can make the coming break appear to be a familiar distributional problem requiring better insurance or macroeconomic management.

That framing is useful for transition management, but it does not confront the ownership question. A high-income employee with rising precautionary savings is not a Sovereign. Unless those savings buy control over AI capital, they are merely a larger ration held by someone whose labor may later become optional.

The Verdict

The paper is a strong account of a real pre-AI symptom and a weak account of the future system. It shows that the upper tier is already exposed to income instability, but it does not model P1, P2, or P3: AI dominance, failed human coordination, and collapse of economically necessary labor.

Its “savings glut of the rich” is not a solution. It is defensive capital formation during the weakening of the old order. The decisive divide will not be between households with stable and unstable income. It will be between those who control the automated production stack and those whose income—however high, volatile, or well-insured—depends on remaining useful to its owners.
