Graeber warns that the current financial order perpetuates violence and exclusion, threatening to implode under its own contradictions.

Graeber opens by exposing the moral confusion at the heart of our assumptions about debt, showing that 'repay your debts' is a moral claim rather than an economic principle. He dismantles Adam Smith's barter myth and rejects primordial debt theory, arguing that credit came first in human history, not barter or coinage. He then builds a new framework of human economies, showing how violence transformed them into market economies across thousands of years. The book traces the cyclical history of virtual credit and coinage from agrarian empires through the Axial Age, the Middle Ages, and the capitalist era. Nixon's removal of the dollar from the gold standard marks a new phase of virtual money, yet the promised stability has not materialized. Graeber concludes with a sharp critique of capitalism and a call to imagine a more just and inclusive financial order.

The US government bails out financial institutions after the Great Recession, leaving ordinary citizens to deal with bankruptcy alone.

Graeber begins writing during the 2008 financial crisis, hoping the moment will spark radical reconsideration of capitalism and its foundations. Through specific examples — from Mesopotamian cuneiform credit tabs to Tiv bridewealth to medieval Islamic free markets — he builds an evidence base for his alternative history of debt. He shows how violence, slavery, and honor are woven into the fabric of market economies from their very beginnings in ancient Greece and Rome. Medieval China's Confucian suspicion of merchants and Islam's ban on interest demonstrate that radically different economic arrangements have been historically possible. In the modern era, Martin Luther's reversal on interest-bearing loans illustrates how moral legitimization of debt transforms entire societies. The US government's decision to bail out banks after the Great Recession ultimately confirms Graeber's argument that capitalism systematically protects creditors over ordinary debtors.

Graeber urges readers to reimagine financial arrangements beyond capitalism, calling on them to act as historical agents of change.

Graeber delivers a series of revelations that upend conventional economic and moral thinking, from showing that Christian theology's language of redemption is rooted in debt to revealing that modern freedom derives from the Roman master-slave relationship.

The Axial Age brings the startling revelation that coins emerged independently across three continents, driven by the shared violence of professional armies. The Tiv's cultural trauma from the slave trade and the story of Cortés recast familiar histories as consequences of debt rather than greed or tradition. John Locke's monetary experiment demonstrates how ideological assumptions about the nature of money can cause real economic catastrophe for ordinary people. Graeber closes by calling on readers to see themselves as historical agents capable of imagining and building a genuinely free financial world.
