Milei Economics: Thatcherism Reborn—or the Last Revolution of Neoliberalism?

When Javier Milei stormed to power in Argentina, clutching a chainsaw and railing against the “political caste,” the symbolism was unmistakable. He came to cut—not to trim. And cut he has: halving ministries, slashing subsidies, firing tens of thousands of civil servants, and promising to abolish the central bank. To some, he is Argentina’s long-overdue Margaret Thatcher—a conviction politician imposing painful medicine on a chronically ill economy. Yet to others, he is the ghost of neoliberalism returned in its most radical, untempered form.

The comparison to Thatcher is tempting but misleading. Both leaders share a common language of market freedom, fiscal austerity, and contempt for state dependency. Both arose amid economic despair, promising discipline after decades of populist excess. Both were vilified by entrenched elites and worshipped by their admirers as saviors of capitalism. But where Thatcher was a reformer within the architecture of a mature democracy and an industrialized nation, Milei is a revolutionary operating on the ruins of one.

Different starting lines: Thatcher’s Britain, Milei’s Argentina

When Thatcher entered Downing Street in 1979, Britain was a tired power suffering from inflation, militant unions, and declining competitiveness—but it still possessed strong institutions, a global currency, and a cohesive civil service. Her reforms—privatization, deregulation, and monetarist stabilization—were painful but manageable.

Milei, by contrast, inherited an economy in collapse. Argentina’s inflation exceeded 200 percent, its currency was toxic, reserves near zero, and public finances a fiscal black hole. After decades of Peronist populism, Argentina’s state had become both employer and debtor of last resort. Into this wreckage strode Milei, armed not with pragmatic monetarism but with Austrian-School theology: abolish the central bank, dollarize the economy, and let the invisible hand repair what decades of state interference had destroyed.

If Thatcherism was a correction, Milei’s project is a purge—an attempt not to reform the state but to erase it.

The monetary leap: from sovereignty to surrender

The sharpest contrast lies in monetary policy. Thatcher defended the independence of the Bank of England and the pound as instruments of national credibility. Her battle against inflation was waged within the bounds of monetary sovereignty.

Milei, however, regards central banking itself as an instrument of tyranny. His plan to abolish the Banco Central and replace the peso with the U.S. dollar represents a leap into post-sovereign territory. To him, money is not a national institution but a free-market commodity—best outsourced to the Federal Reserve. This is not Thatcherism; it is monetary nihilism, a renunciation of the economic tools that anchor a nation’s autonomy.

Even Milton Friedman—Milei’s intellectual idol—defended the need for a stable monetary authority. Thatcher used monetarism to re-establish order. Milei uses dollarization to abandon it.

Austrian roots, anarcho-capitalist bloom

Ideologically, Milei’s economics spring from the Austrian School, particularly Hayek’s defense of spontaneous order and Rothbard’s anarcho-capitalism. He imagines a minimalist state limited to defense and justice, where markets regulate everything else. His admiration for Thatcher is less about policy detail than philosophical kinship: both treat inflation as moral decay and state control as a form of slavery.

Yet Thatcher’s liberalism was bounded by British pragmatism. She privatized industry, not sovereignty. She fought unions, not the idea of society itself. Milei’s libertarianism, by contrast, is theology masquerading as economics—a belief that if only the state were destroyed, prosperity would emerge naturally, like a market Garden of Eden.

The politics of pain

Like Thatcher, Milei insists that there is “no alternative.” Both faced entrenched opposition: Thatcher with trade unions, Milei with Peronist syndicates and public-sector interests. But while Thatcher wielded parliamentary majorities and a disciplined Conservative Party, Milei governs by decree with a fragile coalition and no institutional base.

This makes his austerity infinitely riskier. Thatcher could endure riots and recessions because Britain’s democracy and bureaucracy remained intact. Argentina’s institutions, already brittle, may not withstand another shock. There is a thin line between radical liberalism and authoritarian neoliberalism—a pattern Latin America knows too well from Chile’s Pinochet and Peru’s Fujimori.

Global paradox: a libertarian in a deglobalizing age

There is also a striking geopolitical paradox. Thatcher’s reforms coincided with the high tide of globalization and Reaganite neoliberalism. The world was moving toward free markets, open trade, and financial integration. Milei’s crusade, however, unfolds in the opposite current. The global economy is fragmenting; the U.S. and China are decoupling; and even Western democracies are rediscovering industrial policy and protectionism.

Yet Milei has tied Argentina’s fate to the U.S. dollar and aligned himself ideologically with Washington and Tel Aviv, distancing from Brazil, China, and the BRICS bloc—Argentina’s main trade partners. This Atlanticist stance echoes Thatcher’s alliance with Reagan but defies Argentina’s geopolitical geography. In effect, Milei is applying a 1980s playbook to a 2020s world that has moved on.

Social fracture and economic Darwinism

The social cost is severe. Inflation has eased somewhat, but poverty has deepened. Energy and transport costs have tripled since subsidies were removed. Real wages have collapsed. The middle class—once Argentina’s pride—is evaporating. Milei’s supporters argue that pain is necessary to cleanse decades of fiscal delusion; his critics counter that the medicine may kill the patient before the cure arrives.

Thatcher’s Britain also endured unemployment and inequality, but it had buffers: welfare, rule of law, and a national identity not yet broken by economic despair. In Argentina, austerity is landing on an exhausted society where half the population already lives in poverty. Milei’s libertarian Darwinism—his belief that society must endure suffering to be reborn—risks turning reform into trauma.

A neoliberalism beyond its age

What makes Milei fascinating is that he may represent not the resurgence of neoliberalism, but its final act. His is a creed of absolute faith in markets, unleashed in a world that has lost faith in globalization itself. Thatcher and Reagan built neoliberalism atop industrial democracies; Milei preaches it in a post-industrial, post-trust landscape.

If his program collapses, it could bury the last remnants of laissez-faire idealism in Latin America. But if he succeeds—if inflation falls, growth returns, and Argentina’s fiscal house is restored—he could inspire a libertarian revival across the Global South, where populism has long reigned.

The iron paradox

Ultimately, Thatcherism was never about small government for its own sake; it was about restoring order to a failing system. Milei’s libertarianism, in contrast, treats disorder as virtue—the market’s chaos as divine justice. Thatcher reined in Leviathan; Milei seeks to decapitate it.

The question is whether a society as fractured as Argentina’s can survive the shock. For all her iron will, Thatcher understood one political truth: you can’t reform a nation you destroy.

Milei may yet discover that truth himself—if not through economic data, then through the social fury of a people who may decide that even the most elegant theory cannot substitute for bread.
