The Gini coefficient, a measure of wealth inequality, is 83 in the U.S. today. This places current American society on par with pre-revolutionary France, which had a coefficient between 80 and 85. This stark data point suggests that current economic stratification has reached a level historically associated with major social upheaval.

Inequality itself isn't inherently destructive; it can be a useful incentive for progress. However, societies must avoid "intolerable inequality," a specific threshold where the gap becomes so vast that it predictably triggers societal collapse, a cycle that occurs every 150-250 years.
According to Ray Dalio's historical analysis, today's severe wealth inequality creates irreconcilable political divisions and populism. This pattern mirrors past eras, such as the 1930s, where internal conflict became so intense that several democratic nations chose to become autocracies to restore order.
Extreme wealth inequality creates a fundamental risk beyond social unrest. When the most powerful citizens extricate themselves from public systems—schools, security, healthcare, transport—they lose empathy and any incentive to invest in the nation's core infrastructure. This decay of shared experience and investment leads to societal fragility.
The historic gap between Republican and Democratic pride in America reflects a "K-shaped" economy. A soaring stock market benefits a concentrated few, exacerbating wealth inequality and breaking the social contract. This disconnect between headline market performance and the economic reality for most citizens fuels political division.
As homeownership becomes unattainable without generational wealth, social mobility is stalling. The growing gap between asset owners and renters is calcifying, transforming the American economic structure from a meritocracy into a caste-like system where your financial starting point determines your destiny.
The U.S. economy can no longer be analyzed as a single entity. It has split into two distinct economies: one for the thriving top tier (e.g., AI and tech) and another for the struggling bottom 60%. The entire system now depends on spending from the rich; if they stop, the economy collapses.
Analysis reveals a heavy concentration of spending at the top: the highest decile of income earners is now responsible for 49.2% of all personal outlays. This makes the overall US economy highly dependent on the financial health and confidence of a very small, affluent segment of the population, increasing systemic risk.
Buttigieg frames wealth inequality not just as an economic issue but as an existential threat to the American republic. He states that historically, no republic has been able to maintain its form of government after reaching the current level of wealth and power concentration seen in the U.S.
Historically, what tears societies apart is not economic depression itself but runaway wealth inequality. A major bubble bursting would dramatically widen the gap between asset holders and everyone else, fueling the populist anger and political violence that directly leads to civil unrest.
History demonstrates a direct, causal link between widening inequality and violent societal collapse. When a large portion of the population finds the system unbearable, it leads to events like the French Revolution—a blunt cause-and-effect relationship often sanitized in modern discourse.
