The Insatiable Machine: How Capitalism Became the World’s Dominant Economic System

The Insatiable Machine: tracing how capitalism became the world’s dominant economic system

When historians ask how capitalism “conquered” the world, they are not describing a single invention or a clean handover from older ways of life. They are trying to explain a messy, centuries-long process through which market exchange, private ownership, wage labor, and profit-driven investment expanded—often unevenly, often violently—until they became the default operating system of the global economy. Trevor Jackson’s The Insatiable Machine: How Capitalism Conquered the World arrives into that debate at a moment when capitalism’s reach is unquestioned but its legitimacy is contested, from arguments over inequality and monopoly power to the costs of climate change.

Historical context: from merchants to factories to finance

Capitalism’s roots are usually located in early modern Europe, where long-distance trade, joint-stock companies, and increasingly sophisticated banking helped merchants finance risk and scale. Institutions mattered. The Dutch Republic’s 17th-century commercial ascendancy, built around Amsterdam’s financial innovations and maritime reach, is a classic example of how state capacity, credible public finance, and global trade could reinforce one another. England followed with its own fiscal and commercial transformation after the Glorious Revolution of 1688, including a stronger state credit system and expanding financial markets in London.

But capitalism became more than commerce when production itself was reorganized. The Industrial Revolution—beginning in Britain in the late 18th century and spreading in the 19th—linked mechanization to wage labor and capital accumulation on a new scale. Cotton textiles, powered machinery, coal, and the factory system changed the basic arithmetic of growth. This was not merely “technology.” It was a new social organization: workers separated from land, disciplined by time, paid wages, and producing for markets that were increasingly global.

That global element cannot be separated from empire and coercion. Plantation slavery in the Atlantic world generated enormous flows of cotton, sugar, and profits that fed industrialization and finance; the abolition of slavery did not end coercion so much as reconfigure it, via indenture, colonial taxation, and land expropriation. By the late 19th century, the world economy was more tightly integrated than ever through steamships, railways, and the telegraph, while the gold standard provided a monetary framework for long-distance trade and investment.

Main analysis: what makes the “machine” insatiable?

The most useful way to understand capitalism’s expansion is to focus on its internal logic. Competition pushes firms to innovate, cut costs, and seek new markets; profit encourages reinvestment; reinvestment increases productive capacity; increased capacity demands still larger markets and more inputs. This dynamic creates the sense of an “insatiable machine”—a system with a built-in tendency toward growth, geographic extension, and institutional change.

Three mechanisms have been especially important in capitalism’s world conquest:

1) States and markets grew together, not apart.
The common myth is that capitalism spread by shrinking government. In practice, states built property rights, enforced contracts, issued currency, funded infrastructure, and—crucially—waged wars that reshaped trade routes and colonial possessions. In the 19th century, governments granted charters, protected patents, and sometimes imposed tariffs to nurture “infant industries,” as the United States and Germany did while catching up to Britain. Even the post-1945 liberal order depended on states underwriting reconstruction, social insurance, and rules for trade and finance.

2) Financial systems turned future earnings into present power.
Credit is capitalism’s accelerant. Banks and capital markets allow entrepreneurs and governments to mobilize savings for investment—canals, factories, railways, and later electrification and mass production. Yet finance also creates fragility: booms and busts, panics, and debt crises. From 19th-century banking crises to the Great Depression and the 2008 financial crash, capitalism’s capacity to expand has repeatedly been matched by its capacity to destabilize.

3) Labor and land were reorganized—often forcibly.
Capitalism’s spread relied on creating labor markets and securing inputs. Enclosures and dispossession pushed people into wage work; colonial rule redirected land toward export crops and mining; migration—voluntary and coerced—supplied workforces for plantations, railways, and cities. The “conquest” was therefore not purely economic; it was social and political, remaking households, gender roles, and community life while concentrating decision-making in firms and financial centers.

The 20th century added new layers. The Great Depression discredited laissez-faire and ushered in Keynesian demand management, welfare states, and stronger labor protections in many countries. After 1945, US-led institutions—the IMF, World Bank, and later the GATT/WTO framework—helped stabilize trade and payments, while decolonization created newly sovereign states navigating a capitalist world economy. From the late 1970s onward, deregulation, privatization, and global supply chains deepened market integration, while China’s market reforms after 1978 introduced a hybrid model that married state power to capitalist incentives.

Why it matters

Understanding how capitalism conquered the world clarifies why today’s debates—over inequality, industrial policy, monopolies, and climate—are not anomalies but recurring features. Capitalism generates growth and innovation, but it also produces concentration, periodic crises, and relentless pressure on natural resources. The system’s history shows that outcomes are not predetermined: institutions, politics, and social संघर्ष shape how the “machine” runs, who benefits, and who bears the costs.

Conclusion: a world made, not fated

Capitalism’s global dominance was constructed through a long interplay of markets, states, technologies, and power. It spread because it proved extraordinarily effective at mobilizing investment and raising output—yet it also spread through empire, coercion, and rule-making that favored some regions and classes over others. The lesson for economic history is bracingly contemporary: capitalism is not a natural endpoint. It is a historically contingent system—adaptable, crisis-prone, and, unless governed, genuinely insatiable.
