1980–2008
On October 6, 1979, Paul Volcker, the newly appointed chairman of the Federal Reserve, announced that the central bank would stop targeting interest rates and start targeting the money supply. It was a technical-sounding change that detonated like a bomb. Interest rates shot to 20 percent. Mortgage lending froze. Factories closed. Unemployment climbed past 10 percent, the worst since the Great Depression. And inflation, which had been corroding the American economy for more than a decade, finally broke.
The Volcker shock was the violent birth of the neoliberal era. It established a principle that would dominate the next three decades: price stability was the paramount objective of economic policy, and if achieving it required a punishing recession, so be it. The working class, organized labor, and debtor nations in the developing world bore the heaviest costs. But the inflation dragon was slain, and a new orthodoxy was born.
Ronald Reagan’s election in November 1980, following Margaret Thatcher’s rise to power in Britain the previous year, gave the emerging consensus its political expression. The diagnosis was clear: government was the problem, not the solution. Taxes were too high. Regulations strangled enterprise. Unions held the economy hostage. Public spending crowded out private investment. The prescription followed logically: cut taxes, especially on capital and high earners. Deregulate industry, finance, and labor markets. Privatize state-owned enterprises. Let markets work.
The intellectual foundations had been laid years earlier. Milton Friedman’s monetarism, developed through decades of painstaking empirical work at the University of Chicago, had already displaced Keynesianism as the dominant framework for understanding inflation. Friedman argued that inflation was “always and everywhere a monetary phenomenon” — the result of too much money chasing too few goods — and that the central bank, not the fiscal authority, held the key to macroeconomic stability. His policy prescription was elegant: maintain a steady, predictable growth rate of the money supply and leave everything else to the market.
But neoliberalism was more than monetarism. It drew on Friedrich Hayek’s argument that markets are information-processing systems of unmatched power, capable of coordinating millions of decisions that no central planner could hope to replicate. It drew on the public choice theory of James Buchanan and Gordon Tullock, which applied economic reasoning to politics itself, portraying government officials as self-interested actors who expand their budgets and powers at the public’s expense. And it drew on a renewed faith in the efficiency of financial markets — the hypothesis, formalized by Eugene Fama, that asset prices fully reflect all available information, making regulation not merely unnecessary but counterproductive.
The Washington Consensus, a term coined by economist John Williamson in 1989, codified these ideas into a ten-point policy checklist for developing countries: fiscal discipline, tax reform, trade liberalization, privatization, deregulation, secure property rights, and openness to foreign investment. The International Monetary Fund and World Bank made these reforms conditions for lending, effectively exporting the neoliberal model to Latin America, Africa, Eastern Europe, and Asia. The collapse of the Soviet Union in 1991 seemed to confirm that there was no alternative. Francis Fukuyama famously declared the “end of history” — liberal democratic capitalism had won.
For a time, the results appeared to vindicate the experiment. Inflation remained low and stable across the developed world. Recessions, when they came, were mild. Economists spoke of a “Great Moderation” — a new era of reduced macroeconomic volatility. Alan Greenspan, who chaired the Federal Reserve from 1987 to 2006, was celebrated as a maestro who had mastered the art of monetary fine-tuning. Global trade expanded dramatically. Hundreds of millions of people in China and India were lifted out of poverty as those countries integrated into the world economy.
But beneath the surface of aggregate statistics, structural changes were reshaping the economic landscape in ways that would prove deeply destabilizing. Financial deregulation — the repeal of the Glass-Steagall Act in 1999, the decision not to regulate over-the-counter derivatives, the loosening of capital requirements for banks — allowed the financial sector to metastasize. Finance grew from roughly 4 percent of American GDP in 1980 to nearly 8 percent by 2006. Wall Street’s profits as a share of total corporate profits tripled. The sector attracted a disproportionate share of the nation’s mathematical and engineering talent, lured by compensation packages that dwarfed anything available in productive industry.
Income inequality widened relentlessly. In the United States, the share of national income captured by the top 1 percent roughly doubled between 1980 and 2007, returning to levels not seen since the eve of the Great Depression. Real wages for the median worker stagnated even as productivity rose, breaking the postwar link between growth and broadly shared prosperity. The gains from globalization and technological change were captured overwhelmingly by those at the top of the distribution. For those in the middle and at the bottom, the promise that deregulation and tax cuts would “trickle down” rang increasingly hollow.
The Asian Financial Crisis of 1997 was an early warning. Economies that had been held up as miracles of market-led development — Thailand, Indonesia, South Korea — collapsed virtually overnight as hot money fled and currencies cratered. The IMF’s response, demanding fiscal austerity and structural reform from countries already in free fall, deepened the suffering and generated lasting resentment. Joseph Stiglitz, then chief economist of the World Bank, publicly broke with the Fund’s approach, arguing that its policies were making crises worse, not better.
The dot-com bubble and bust of 2000-2001 offered another signal. The Federal Reserve had kept interest rates low through the late 1990s as equity prices soared to levels disconnected from any plausible earnings forecast. When the bubble burst, erasing trillions in paper wealth, the Fed responded by cutting rates even further — inadvertently inflating the next bubble, this time in housing.
The Global Financial Crisis of 2008 was the reckoning. It was not an accident or an act of God. It was the logical product of three decades of financial deregulation, lax supervision, and a collective delusion that sophisticated mathematical models had tamed risk. Mortgage lenders extended credit to borrowers who could never repay. Investment banks packaged those mortgages into securities and sold them worldwide. Rating agencies stamped them with triple-A grades. And when the housing market turned, the entire edifice collapsed.
Lehman Brothers filed for bankruptcy on September 15, 2008. Global credit markets seized. International trade plummeted at a rate not seen since the 1930s. Governments that had spent decades proclaiming the superiority of markets over states found themselves nationalizing banks, guaranteeing deposits, and running deficits that would have been inconceivable a year earlier. The irony was savage: the neoliberal era ended with the largest government interventions in economic history.
The crisis did not produce a clean break with neoliberalism in the way that the Depression had discredited laissez-faire or stagflation had buried Keynesianism. There was no new Keynes, no single theoretical framework waiting to replace the old one. Instead, what emerged was a muddled, contested landscape — austerity in Europe, stimulus in China, quantitative easing everywhere — and a growing recognition that the questions the neoliberal era had claimed to settle were, in fact, wide open. How much should the state regulate finance? How should the gains from trade and technology be distributed? Is perpetual growth on a finite planet possible, or even desirable? The neoliberal era did not answer these questions. It sharpened them, painfully, and left them for the rest of us.
