Milton Friedman

By Lin Yue

Milton Friedman was born in 1912 in Brooklyn, the son of Jewish immigrants from the Austro-Hungarian Empire, and grew up in New Jersey in a household where money was scarce and argument was plentiful. He won a scholarship to Rutgers, then to Chicago, and emerged as the most consequential economist of the second half of the twentieth century — the man who broke Keynesianism's grip and rebuilt economics around a single, devastating sentence: inflation is always and everywhere a monetary phenomenon.

The demolition began with history. With Anna Schwartz, Friedman wrote A Monetary History of the United States (1963), a thousand-page forensic examination arguing that the Great Depression was not a failure of capitalism but a failure of the Federal Reserve, which had allowed the money supply to collapse by a third. The implication was dynamite: the central bankers who claimed to manage the economy had caused its greatest catastrophe. Keynesians never fully recovered.

Then came theory. The permanent income hypothesis (1957) argued that households spend based on lifetime expected income, not current paychecks — which meant Keynes's multiplier was weaker than advertised and fine-tuning the economy was largely an illusion. His 1968 presidential address to the American Economic Association introduced the "natural rate" of unemployment and expectations-augmented Phillips curve: try to push unemployment below its natural level with inflation, and people will see through it, demand higher wages, and leave you with both inflation and unemployment. Within a decade, stagflation proved him right in the most painful possible way.

Friedman was also a public crusader. Capitalism and Freedom (1962) made the moral case for markets — school choice, a volunteer army, the negative income tax, drug legalization — and the television series Free to Choose (1980) carried it into living rooms. His 1975 visit to Chile, where his former students advised Pinochet's junta, stained his reputation among the left forever; he insisted he counseled free markets, not dictatorship, and that economic freedom would undermine tyranny. The argument remains unresolved.

He won the Nobel in 1976 and died in 2006, having lived to see central banks worldwide adopt his creed: control the money, target inflation, and leave the rest to markets. The Keynesian palace he stormed now flies his flag.

His debating style was legendary — rapid, cheerful, merciless. On television and in lecture halls he dismantled opponents with a smile, turning complex arguments into plain sentences: "There's no such thing as a free lunch." He and his wife Rose were a team in everything, co-authoring the books that carried his ideas beyond the academy. Even his enemies conceded the performance: watching Friedman argue was watching intellect as a contact sport.

Impact on civilization

Friedman's ideas govern the money in your pocket. When Paul Volcker crushed American inflation in the early 1980s by strangling the money supply — accepting brutal recession as the price — he was executing Friedman's doctrine, and every inflation-targeting central bank since, from Frankfurt to Tokyo, operates in the world Friedman built. The volunteer US military, school voucher debates, and the earned-income tax credit all trace to his proposals. Intellectually, he restored the quantity theory of money, founded modern monetary economics, and gave free-market liberalism its most formidable twentieth-century voice. His legacy is double-edged: price stability for billions, and a suspicion of the state that reshaped politics — for better and worse — across the globe.

The global wave of central bank independence — the idea that money must be insulated from politicians — is Friedman's institutional legacy, now orthodoxy from Warsaw to Wellington. Education reform movements worldwide still march under his school-choice banner. And his methodological insistence that theories be judged by predictions, not assumptions, permanently toughened economics' empirical standards.
