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.

While societal decline can be a long, slow process, it can unravel rapidly. The tipping point is when the outside world loses confidence in a nation's core institutions, such as its legal system or central bank. This triggers a sudden flight of capital, talent, and investment, drastically accelerating the collapse.
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.
Economist Thomas Piketty's theory that inequality grows indefinitely was historically countered by the complementarity of labor and capital. However, AI could make capital a full substitute for labor, breaking the market's self-correcting mechanism and validating Piketty's thesis for the future.
The ability to print money creates inflation that widens the wealth gap. This hyper-inequality triggers a deep-seated, evolutionary psychological response against unfairness, which then manifests as widespread social unrest and societal breakdown.
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.
Robert Solow posits that rising inequality isn't just an economic issue; it's a political one. Initial economic disparities lead to political inequality, which then allows the powerful to shape laws (like deregulation) in their favor, further concentrating wealth and reinforcing the initial inequality.
Current instability is not unique to one country but part of a global pattern. This mirrors historical "crisis centuries" (like the 17th) where civil wars, plagues, and economic turmoil occurred simultaneously across different civilizations, driven by similar underlying variables.
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.
Political violence and societal decay are not random events but predictable outcomes of economic desperation. By analyzing quantifiable data like debt-to-GDP ratios on a spreadsheet, one can forecast these outcomes with high accuracy. Because the problem is knowable and data-driven, it is also avoidable.
