Introduction
You live in a world of unimaginable material abundance, yet you likely wonder why economic security and social harmony remain perpetually out of reach. You experience a constant tension between technological miracles and persistent inequality, political instability, and recurring crises. Bradford DeLong calls the period from 1870 to 2010 the long twentieth century, during which humanity unlocked the secrets of sustained economic growth.
Between 1870 and 2010 humanity achieved unprecedented material abundance through technological revolution and globalization, yet failed to secure sustainable happiness or solve the problem of equitable distribution.
The book explores how the market economy was born, how it conquered scarcity, and why humanity struggled to govern its own creations. You will discover how globalization, corporate research laboratories, and mass production transformed civilization. You will also examine why material wealth failed to prevent devastating world wars and economic depressions. The narrative addresses several core questions:
- How did humanity finally escape the Malthusian trap of permanent poverty?
- Why did the triumph of the market fail to bring universal human fulfillment?
- How did political ideologies and state interventions shape the modern economy?
- What caused the transition from post-war social democracy to neoliberalism?
1. The Malthusian Trap and the 1870 Turning Point
Before 1870, human populations were trapped by the Malthusian Devil, where any increase in technological capability or agricultural productivity was quickly consumed by population growth, keeping the standard of living near bare subsistence.
Before 1870, humanity remained trapped in subsistence-level stagnation where any technological gain was rapidly consumed by population growth, until a quadruple jump in innovation permanently broke the cycle.
Thomas Malthus argued that human sexuality naturally drives population growth to the limits of food supply. You can see this through positive checks like malnutrition and disease or preventive checks like delayed marriage and patriarchy. Throughout the Agrarian Age and the Commercial Revolution, output growth failed to outpace population, leaving real wages stagnant for centuries.
Greg Clark estimated English construction-worker real wages over time, showing that wages in 1800 were virtually identical to those in 1650, 1340, 1260, and 1230, with only temporary spikes following plagues like the Black Death of 1346–1348.
In 6000 BCE, world population was perhaps 7 million people with a technological index of 0.051. By the year 1, world population reached roughly 170 million and a technological index of 0.25. From 1000 BCE to 1500 CE, human populations grew at a rate of 0.09 percent per year, increasing from 50 million to 500 million. By 1800, real wages of English construction workers were set at an index value of 100.
The Post-1870 Economic Explosion
The Industrial Revolution marked a watershed boundary crossing that tripled the growth rate of technological capabilities. It was still insufficient on its own to permanently break free from population expansion.
Beginning around 1770, the growth rate of technological and organizational capabilities jumped from 0.15 percent to roughly 0.45 percent per year in the heartland of Britain and North America. High birth rates and rapid population growth threatened to consume these gains. Experts like John Maynard Keynes and William Stanley Jevons feared that humanity would eventually exhaust its resources and return to stagnation.
William Stanley Jevons published The Coal Question in 1865, arguing that Britain would soon run out of accessible coal and bring factories to a halt.
From 1770 to 1870, global population growth accelerated to about 0.5 percent per year. In 1870, more than four-fifths of humans still tilled the earth for food. From 1870 to 2016, global copper mining increased from 5 ounces to 5 pounds per person, and steel production rose from 1 pound to 350 pounds per person.
Around 1870, a third watershed boundary crossing occurred as the growth rate of technological and organizational capabilities quadrupled. This permanently outran population growth and created an economic El Dorado.
The proportional rate of technological and organizational progress surged to about 2.1 percent per year. This explosion of innovation, combined with the rise of industrial research laboratories and large modern corporations, allowed technology to far outstrip population growth. It initiated a decline in fertility among wealthier economies.
In the economic El Dorado period from 1870 to 1914, Britain burned 194 million tons of coal in 1914. Real wages of unskilled workers globally rose to half again above their 1870 levels.
2. Globalization, Migration, and the Global Divide
The late nineteenth century forged the first integrated global economy through mass migration and transport revolutions, yet drove a severe economic divergence between the industrializing core and the primary-producing periphery.
Mass Migration and Transport
You witness an unprecedented redistribution of humanity between 1870 and 1914. One hundred million people changed their continent of residence. The iron-hulled steamship, the railroad, and the submarine telegraph enabled this massive shift.
Global railway mileage increased from 20,000 miles to 300,000 miles between 1865 and 1914. International trade as a proportion of total world production grew from 1.5 percent in 1500 to 17 percent in 1913. The proportion of global economic activity traded across borders rose from 9 percent to 15 percent between 1870 and 1914.
Europeans moved to temperate-zone lands, while Asian migration was largely restricted or directed to plantations. Mohandas Karamchand Gandhi sailed to England to study law in 1888. He later went to South Africa in 1893 to collect a debt and stayed for twenty-two years. This experience transformed him into an anti-imperialist politician.
The First Unbundling and Divergence
Richard Baldwin calls this separation of production from consumption the first unbundling. The price of flour shipped from Chicago to London dropped from 3 cents to 2 cents per pound between 1850 and 1890.
Goods could be produced where cheapest and consumed anywhere. Manufacturing clustered in the global north due to communication costs and established communities of engineering practice. Meanwhile, the global south specialized in low-value primary products and plantation agriculture.
Egypt's Khedive Muhammed Ali attempted to industrialize with textile factories in the early nineteenth century. Maintaining the machinery failed. This left his grandson Ismail as a puppet of European bankers.
Robert Allen argued that colonial governments refused to adopt the standard package for industrialization. These regions lacked the necessary components:
- ports
- railways
- schools
- infant industry tariffs
Britain exercised global economic dominance through an informal empire. By leveraging free trade, concentrated industry, free migration, and freedom of investment, Britain integrated the global economy. This informal mode systematically peripheralized non-industrial regions into producing primary products.
3. The Second Industrial Revolution and Corporate Capitalism
Advanced economies invented the systematic invention of technology after 1870, deploying electrical grids, steel production, and corporate research laboratories that transformed material civilization.
Technological Acceleration
Between 1870 and 1914, technology and organization improved at a rate of 2 percent per year. This pace was more than quadruple the growth rate from 1770 to 1870. You saw societies create industrial research labs and large corporations to deploy new technologies at a national and continental scale.
Universal expositions celebrated commerce, trade, and the wonders of modern technology. For example, the 1889 Paris exposition featured Gustave Eiffel's tower.
Materials, Infrastructure, and Creative Destruction
The development of modern steel production in the mid-nineteenth century drastically dropped the cost of the master metal of industrial civilization. Manufacturers used the Bessemer-Mushet, Thomas-Gilchrist, and Siemens-Martin processes to burn off impurities from molten cast iron. They added back precise amounts of carbon and manganese to produce industrial steel efficiently.
Henry Bessemer and Robert Mushet developed a process in 1855-1856 that forced air through molten cast iron. This caused the price of a ton of steel to drop from £45 down to £6. By 1914, worldwide steel production reached 70 million tons a year.
Nikola Tesla's alternating current electrical system triumphed over Thomas Edison's direct current system by enabling efficient long-distance power transmission through transformers. Direct current suffered severe energy losses to heat over distance, requiring a power plant in every neighborhood. Alternating current shook electrons back and forth via magnets, allowing high voltage transmission over long distances. Step-down transformers then stepped down the voltage safely, leveraging economies of scale.
Nikola Tesla arrived in New York in 1884 with a recommendation letter to Thomas Edison. Edison promised Tesla $50,000 for redesigning DC generators. Tesla later broke away after a payment dispute and partnered with George Westinghouse to win the war of the currents by illuminating the 1893 Chicago World's Fair.
Capitalist economic growth inherently relied on creative destruction, where continuous technological innovations generated massive wealth while simultaneously destroying old industries and imposing uncertainty. Market economies constantly revolutionized the economic structure from within through new consumer goods, production methods, and industrial organizations. In 1942, Joseph Schumpeter described this capitalist creative destruction.
Financiers intervened to rationalize operations and sideline visionary inventors. For example, financiers such as J.P. Morgan and George F. Baker intervened in 1907 to sideline visionary inventors like Nikola Tesla and install sober executives focused on dividends and cost-cutting.
Henry Ford revolutionized manufacturing by combining the American system of interchangeable parts with the moving assembly line, high-capital intensity, and high wages. Ford minimized costs and lowered prices by focusing on high-volume production of a single standardized product rather than custom luxury goods. He enforced the pace of work using assembly lines and combated extreme worker turnover by drastically increasing daily wages.
Workers paid standard wages of slightly less than $2 a day quit at astonishing rates. In 1913, Ford experienced a 370 percent turnover rate with 50,400 workers quitting or being fired from a 13,600-person workforce. Introducing a $5 a day wage for unskilled workers reduced annual turnover down to 16 percent by 1915.
4. Global Empires and the Institutional Exception
While informal and formal imperialisms integrated global trade, non-Western regions largely stagnated due to institutional and political failures, with the notable exception of Meiji Japan.
Colonial Case Studies
The introduction of internal peace and a tolerable administration of justice did not automatically generate high economic progress in India. Despite providing conditions that economists like Adam Smith deemed sufficient for opulence, the British Raj failed to transform India. Modern industry, education, agricultural productivity, and the caste system remained largely unchaperoned by true development.
After Robert Clive bribed subordinates of the Nawab of Bengal following the capture of Calcutta in 1756, the British East India Company gradually transformed from a trading entity into a governing power. This expansion culminated on May 1, 1876, when the British government proclaimed Queen Victoria I Hanover to be Kaiser-i-Hind, the Empress of India.
Late imperial China's bureaucratic and cultural structure obstructed industrial development by prioritizing patronage networks over technical competence. Reformers like Li Hongzhang attempted self-strengthening efforts such as modern coal mines and arsenals. They faced intense opposition from conservative officials who claimed modern methods angered earth dragons, eventually leading to corruption and foreign takeovers.
The Kaiping coal mine, established in 1881, was later reincorporated under British control by Herbert Hoover in 1901 after political fixers padded payrolls and prioritized court patronage over production. By 1929, China produced 20,000 tons of steel, which was less than 2 ounces per person. It produced 400,000 tons of iron, or 1.6 pounds per person, and mined 27 million tons of coal, or 100 pounds per person.
The Japanese Exception
Japan successfully industrialized and avoided colonization by intentionally adopting Western technology and organization while preserving Japanese spirit. Guided by the slogans of Wakon yosai and Fukoku kyōhei, the Meiji leadership rapidly established compulsory schooling, central taxation, a national railway and telegraph system, and government subsidies for successful exporters.
You can understand the Meiji path through the prerequisites that economic historian Robert Allen formulated for nations to step onto the escalator to prosperity.
Economic growth required nations to work through these specific steps:
- have a stable, market-promoting government;
- build railroads, canals, and ports;
- charter banks for commerce and investment;
- establish systems of mass education;
- impose tariffs to protect industries and communities of engineering practice;
- execute a Big Push to set virtuous circles of economic development in motion.
Following the Meiji Restoration in 1868, leaders like Itō Hirobumi studied Western banking and institutions. They established industrial infrastructure and successfully defeated China in 1895 and Russia in 1905, reaching a milestone by 1890 where 80 percent of school-age children were at least enrolled in school. Most economies in the global south failed to work through this checklist because pre-World War II colonial masters did little to prepare them for independent prosperity.
5. The Clash of Ideologies and the Great War
Nationalism and militarism shattered the liberal global order in 1914, proving that material wealth could not prevent a catastrophic war driven by competing ideological switchmen.
Hayek versus Polanyi
Friedrich Hayek argued that market economies distribute rewards based on timing and location rather than moral desert. Social justice becomes chimerical and dangerous under his framework.
Hayek maintained that attempting to centrally plan income redistribution destroys the price mechanism. You lose decentralized information flow, which inevitably leads down the road to serfdom.
Karl Polanyi argued that treating land, labor, and finance as pure commodities provokes a powerful social backlash. This reaction operates through a double movement.
People believe they possess inherent economic rights to stable communities and secure purchasing power. Society inevitably intervenes to re-embed the market in moral governance.
The Collapse of Internationalism
Norman Angell argued before World War I that war and territorial conquest had become economically irrational. Conquest yielded no material advantage in the age of industrial trade.
Norman Angell published The Great Illusion in 1909 and followed it with Peace Theories and the Balkan War. He pointed out that small neutral states like Belgium had higher government bond values than powerful empires like Germany. Although he correctly deduced that war makes no economic sense, he was disastrously wrong in assuming humanity had outgrown it.
Nationalist ideology acted as a powerful switchman guiding material interests toward destructive imperialist conflicts. Max Weber and other nationalist intellectuals prioritized cultural dominance and geopolitical elbow-room over economic rationality.
Max Weber articulated his nationalist worldview in his 1895 inaugural Freiburg university lecture, The National State and Economic Policy.
World War I destroyed the stable liberal economic order of the long nineteenth century at an immense human and political cost.
The conflict caused approximately 10000000 deaths among the major European belligerents, alongside millions of injuries and a total death toll reaching 50000000 when including the 1918-1919 Spanish flu epidemic amplified by war. You saw four major empires collapse as the laughter of the guns wiped out a generation of young men.
6. The Interwar Economic Crisis and the Great Depression
The absence of a global hegemon, combined with the gold standard and liquidationist economic doctrines, converted an initial financial panic into the longest and deepest economic depression in history.
Economies require a leading state whose citizens ship the most exports, import the most, and lend capital to manage the global system. Britain could no longer play this role, and the United States refused to step into it, instead turning toward isolationism and letting global public interest collapse. President Woodrow Wilson attempted to secure the League of Nations, but Senator Henry Cabot Lodge and his Republican peers refused to commit the United States to an internationalist foreign policy.
The punitive reparations imposed on Germany at the Treaty of Versailles triggered a destructive hyperinflation that destabilized the Weimar Republic. Financiers demanded exorbitant returns due to the political toxicity of reparations. The German government chose to print money rather than collect sufficient taxes or negotiate feasible long-term ownership shares with the Allies. Prices in Germany rose a trillionfold, with what cost 4 Reichsmarks in 1914 costing 4 trillion by the end of 1923. In 1914 the Reichsmark was worth 25 US cents, dropping to 0.000000000025 of a cent by the end of 1923. The French army occupied the Ruhr Valley in January 1923 to collect commodities at gunpoint, prompting a general strike supported by the German government through massive money printing.
Origins and Policy Failures of the Great Depression
The Great Depression was triggered by Federal Reserve monetary tightening aimed at curbing stock market speculation and preventing gold outflows. Beginning in 1928, the Federal Reserve raised interest rates to choke off gold outflows and speculative overvaluation. These contractionary measures successfully defended gold reserves but pushed the U.S. economy into a cyclical downturn by June 1929. Economists Milton Friedman and Anna Schwartz argued that the Federal Reserve was overly contractionary in the run-up to the 1929 crash, counterproductively triggering a recession.
The Great Depression was far deeper and longer than any previous or subsequent economic downturns due to a cascading series of banking panics and collapsing confidence. Unlike earlier downturns that featured a single shock, the Great Depression involved initial recessionary shocks, a stock market crash, and subsequent waves of banking panics in 1930 and 1931 that destroyed trust in bank deposits. Peak unemployment reached 12 percent in 1894, 6 percent in 1908, 11 percent in 1921, and 23 percent during the Great Depression in the United States, alongside 28 percent for nonfarm workers.
Policy elites embraced liquidationist and austerity doctrines, believing that allowing mass unemployment and deflation to purge the system was healthy medicine rather than a disease to be cured. Treasury Secretary Andrew Mellon and economists like Joseph Schumpeter and Friedrich von Hayek argued that depressions were necessary adjustments to liquidate malinvestments. Treasury Secretary Andrew Mellon's formula was to liquidate labor, liquidate stocks, liquidate the farmers, and liquidate real estate to purge rottenness out of the system. German chancellor Heinrich Brüning decreed 10 percent price cuts and 10 to 15 percent wage cuts while central banks and governments maintained balanced budgets.
Governments can cure depressions caused by liquidity shortages by injecting cash into the public's hands, because the government's ability to accept its own money for taxes makes it uniquely trusted. When an economy freezes due to a shortage of demand, the government can increase the money supply through central bank asset trades, direct hiring, buying useful goods, or distributing cash directly. Milton Friedman proposed throwing bundles of cash from helicopters, which earned former Federal Reserve chair Ben Bernanke the nickname Helicopter Ben.
To overcome a liquidity shortage, you can use these methods:
- Have government functionaries throw bundles of cash out of helicopters
- Hire people, set them to work, and pay them
- Buy useful stuff to provide extra demand for employers to hire more people
- Use a central bank to trade financial assets for cash
7. Totalitarian Alternatives and World War II
Disillusioned by market failures, nations turned to totalitarian extremes of fascism and Soviet central planning, ultimately necessitating total industrial mobilization to defeat the Axis powers.
The Soviet Experiment
Lenin modeled war communism on World War I Germany's centrally directed war economy, using material balances and coercion to run industry without private property or markets. Central planners issued demands, utilized material balances, and forced managers to rely on blat, barter, and tolkachi when official planning failed.
Factory managers had to beg, borrow, barter, buy, and steal resources over and above those directed to them to fulfill the state plan. Lenin failed to secure a political succession mechanism, enabling Joseph Stalin to leverage his control over personnel as general secretary to consolidate total dictatorial power. Stalin used his appointment powers over local committee secretaries to stack party congresses, systematically executing or exiling all his former Politburo peers and rivals.
To finance rapid industrialization without consumer goods, Stalin waged economic war on the peasantry through forced collectivization, causing mass famine and millions of deaths.
Peasant farmers slaughtered and ate their farm animals before government bureaucrats arrived to take them. Ninety-four percent of the Soviet Union's twenty-five million peasant households gathered into state and collective farms. This policy resulted in an estimated fifteen million deaths during the agricultural disaster of the 1930s, with an average of fifty peasants per collective farm.
Fascism and Totalitarian Commonalities
Between the world wars, three totalizing ideologies confronted each other demanding fundamental economic and society restructuring: market worship, really-existing socialism, and fascism. Adolf Hitler applied a Malthusian trap framework combined with social Darwinism to foreign policy, arguing that Germany required violent territorial expansion eastward to feed its growing population. Hitler enlisted in the Bavarian Army in August 1914, joined the 16th Bavarian Reserve Regiment, and was wounded in 1916 and temporarily blinded by a gas attack in October 1918. He detailed these views in the 1925 publication year of Mein Kampf, rejecting peaceful alternatives to population pressure.
The Industrial Turn and Victory
Once World War II became truly global, Nazi Germany's defeat became inevitable due to the overwhelming industrial and economic outproduction of the Allies. By 1944, Allied war production reached an index of 150 compared to just 24 for Germany and Japan combined. This massive disparity resulted in approximately sixty million people dying from World War II before the industrial might of the Allies crushed the Axis powers.
8. The Post-War Golden Age and Neoliberal Turn
The post-WWII mixed economy delivered thirty glorious years of growth and social democracy before unanchored inflation and stagflation triggered a neoliberal counter-revolution.
Thirty Glorious Years of Social Democracy
The US Marshall Plan provided crucial financial aid and hard currency to Western Europe, but its primary economic benefit came through political stabilization and relaxed foreign exchange constraints. From 1948 to 1951, the United States contributed $13.2 billion to European recovery, including $3.2 billion to the UK, $2.7 billion to France, $1.5 billion to Italy, and $1.4 billion to Western-occupied Germany. Marshall Plan funds helped cover immediate shortages of essential goods like coal, cotton, and petroleum, while tying aid to strict governmental budget balancing and financial stabilization requirements. Post-World War II Western European nations successfully built robust social democratic mixed economies that combined large welfare states with reliance on market allocation. By 1951, national incomes per capita in Britain, France, and Germany exceeded prewar levels by more than 10 percent.
The collapse of macroeconomic stability in the late 1960s and 1970s was caused by unanchored inflation expectations and overambitious attempts to push unemployment below sustainable floors. When the Johnson administration sought to drive unemployment below 5 percent through monetary expansion and deficit spending, inflation expectations became unanchored. President Richard Nixon attempted to combat inflation by imposing wage and price controls and suspending the Bretton Woods pegged exchange rate system after traditional monetary tightening failed to reduce inflation quickly.
The Neoliberal Turn and Hyperglobalization
The domestic economic policies of Ronald Reagan and Margaret Thatcher failed to accelerate growth or shrink government, instead producing large budget deficits and widening inequality. While promising to boost investment and reduce government size through tax cuts and deregulation, their policies resulted in massive budget deficits because spending cuts failed to materialize. The US dollar remained substantially overvalued for more than half of the 1980s because federal budget deficits sucked in foreign capital, hammering American Midwestern manufacturing and helping create the Rust Belt.
The information technology revolution enabled a second unbundling of intra-firm communication, transforming reglobalization into hyperglobalization through global value chains. Apple Computer maintained fifty first-class seats daily between San Francisco and China prior to the COVID-19 pandemic. By 2010, 9 percent of the world population lived on less than US$2 per day.
The Great Recession of 2007-2009 was neither a monetarist nor a Keynesian depression, but a Minskyite depression characterized by an extreme shortage of safe stores of value. Major commercial banks were simultaneously the largest creators and buyers of securitization products, buying each other's toxic assets under the false assumption that AAA ratings guaranteed safety without auditing the underlying models. The crisis destroyed between $60 trillion and $80 trillion in wealth after panic selling set in, pushing the US unemployment rate to 10 percent in late 2009.
A Minskyite depression requires the execution of the Bagehot-Minsky playbook, which demands that governments and central banks lend freely on normally good collateral but at a penalty rate.
A Minskyite depression requires specific policy responses:
- Lend freely to create enough safe assets so they are no longer in short supply.
- Use collateral that is good in normal times to separate temporarily troubled institutions from permanently insolvent ones.
- Apply a penalty rate to discourage opportunistic financiers from exploiting the crisis situation.
Conclusion
Between 1870 and 2010 humanity achieved unprecedented material abundance through technological revolution and globalization, yet failed to secure sustainable happiness or solve the problem of equitable distribution. You now possess the long historical view of how humanity escaped the Malthusian trap only to build a turbulent global economy driven by markets and technological dynamism. The central lesson is that economic mechanisms create immense wealth, but they cannot automatically guarantee social harmony or distributive justice. You must navigate a world where material scarcity is conquered, but ideological conflict and economic volatility remain.
To manage modern economic policy and secure prosperity, you should apply these practical rules:
- Maintain strong social insurance programs to protect citizens against market failures, unemployment, and economic shocks.
- Reject unyielding dogmas of pure free markets or total state planning in favor of pragmatic mixed economies.
- Regulate financial systems strictly to prevent speculative manias from triggering catastrophic depressions.
- Invest continuously in technological innovation and public infrastructure to sustain long-term economic growth.
- Foster international cooperation to manage global trade, migration, and ecological challenges without resorting to destructive nationalism.
