The Great Leveler by Walter Scheidel: Study & Analysis Guide

Walter Scheidel’s The Great Leveler presents a stark, challenging thesis about a problem that defines our age: economic inequality. He argues that across millennia, significant and lasting reductions in the concentration of wealth and power have almost never been achieved by peaceful means. Instead, history shows that only catastrophic, violent upheavals have acted as reliable forces for leveling. Understanding this provocative argument is crucial for grappling with the roots of inequality and evaluating our prospects for a more equitable future.

The Core Thesis: Violence as the Great Compressor

Scheidel’s central argument is that economic inequality is the natural, default state of complex societies. Left unchecked, wealth concentrates in the hands of a few through mechanisms like inheritance, rent-seeking, and the political capture of institutions. Peaceful reform and policy interventions, while well-intentioned, have historically been too feeble, too reversible, or too co-opted to produce durable leveling on a large scale. The book surveys an immense chronological scope, from the Stone Age to the present, to demonstrate that this pattern holds true across different cultures and economic systems. The unsettling conclusion is that what Scheidel terms "the Great Leveling" of the mid-20th century was not a triumph of progressive policy but a tragic byproduct of unimaginable violence.

The Four Horsemen of Leveling

Scheidel identifies four catastrophic forces, which he metaphorically calls the Four Horsemen of leveling, as the only reliable compressors of inequality. These are not abstract concepts but specific, violent historical processes.

1. Mass Mobilization Warfare: Total war, like the World Wars, forces societies to mobilize all resources. This leads to progressive taxation, the destruction of capital, inflation that erodes financial assets, and a collective bargaining power for labor that compresses the income gap. The mid-20th century leveling, Scheidel contends, was primarily a result of these conflicts.
2. Transformative Revolution: Violent, communist-style revolutions, such as those in Russia and China, directly and forcibly expropriate the wealth of elites and dismantle existing property structures. This creates dramatic leveling, but at an enormous human cost and through authoritarian means.
3. State Failure and Societal Collapse: The complete disintegration of a state, as seen with the fall of the Roman Empire, destroys the complex institutions that sustain and protect elite wealth. In the resulting chaos and simpler economies, the gap between the rich and poor narrows simply because the mechanisms for storing and generating vast wealth vanish.
4. Devastating Pandemics: Catastrophic plagues, like the Black Death, cause a severe shortage of labor. This dramatically increases the bargaining power of workers (serfs or peasants) relative to landowners, leading to higher wages and lower rents, thereby redistributing income. The key is the scale of mortality, which must be high enough to overwhelm societal structures.

The Historical Survey and the Case Against Peaceful Reform

The book’s power lies in its exhaustive historical evidence. Scheidel examines ancient Rome, medieval Europe, imperial China, and other civilizations, showing how inequality tended to rise during periods of stability and peace. He scrutinizes instances often cited as peaceful reforms—such as the democratizations of the 19th and 20th centuries, the New Deal, or social democracy in post-war Europe—and argues that their leveling effects were either limited, temporary, or, in the case of the mid-20th century, fundamentally underpinned by the shadow of the World Wars and the Cold War. From this vantage point, policies like progressive taxation or social welfare are seen as products of a violent shock to the system, not as independent causes of leveling. Once the memory of the catastrophe fades, inequality slowly but surely creeps back, as evidenced by trends since the 1980s.

Critical Perspectives

While Scheidel’s historical evidence is formidable and his thesis is intellectually provocative, it has drawn significant critique. Engaging with these criticisms is essential for a balanced analysis.

• Risk of Deterministic Conclusion: The most serious charge is that the argument can become a self-fulfilling prophecy. If we are convinced that only catastrophe can level, we may abandon faith in democratic politics and policy, thereby ensuring that peaceful reform remains impossible. It can foster a cynical paralysis that serves the interests of the status quo.
• Underweighting Recent Policy Success: Critics argue Scheidel underweights examples of successful, non-catastrophic intervention. The significant reduction of inequality in many Latin American countries in the early 21st century through conditional cash transfers and other policies, or the more stable equality in some Nordic states, suggest policy can matter outside the immediate aftermath of a Horseman. The book’s broad historical sweep may not fully capture the novel institutional tools of modern states.
• Defining "Lasting" and "Significant": The debate often hinges on definitions. How long must leveling last to be considered durable? How much reduction is significant? Critics note that even temporary or partial reductions achieved through policy can have profound moral and social value, even if they are eventually partially reversed.
• The Fifth Horseman?: Some scholars speculate whether climate change, as a systemic, global catastrophe, could act as a new, non-traditional "Horseman" of leveling, or whether it might instead exacerbate inequality further. Scheidel’s framework forces us to confront this grim question.

Summary

• The Default State is Inequality: Scheidel argues that in settled, complex societies, wealth concentration is the natural, resilient trend.
• The Four Horsemen are Key: Only four types of catastrophic violence—mass mobilization warfare, transformative revolution, state collapse, and devastating pandemics—have proven capable of forcing major, lasting reductions in inequality throughout history.
• Peaceful Reform Has Historical Limits: The book presents exhaustive evidence that institutional reforms without the context of catastrophic violence have consistently failed to achieve large-scale, permanent leveling.
• A Provocative, Not Prescriptive, Thesis: Scheidel is diagnosing a historical pattern, not advocating for violence. The value of the book is in its power to challenge comforting assumptions about progress.
• Beware of Fatalism: The major critique is that accepting the thesis as deterministic can undermine efforts at peaceful reform, creating a self-fulfilling prophecy of failure.
• Modern Context Matters: While historically robust, the thesis may underweight the unique potential of modern policy tools and the novel global challenges, like climate change, that could alter the historical equation.
