Milton Friedman (1912-2006) was an American economist and public intellectual whose work shaped modern macroeconomics, monetary theory, and economic policy debates across the second half of the twentieth century. He is most closely associated with monetarism-the view that the money supply is the primary determinant of short-run economic output and long-run price levels-and with advocacy for free markets, limited government, and individual liberty. Friedman's broader legacy, including the normative implications of his economic framework and its effects when applied to policy, remains contested across political and scholarly traditions.
Friedman spent the bulk of his academic career at the University of Chicago, where he became the central figure of what came to be called the Chicago School of economics. His 1963 collaboration with Anna Schwartz, A Monetary History of the United States, 1867-1960, argued that the Federal Reserve's contraction of the money supply transformed a recession into the Great Depression-a thesis that reshaped how economists and policymakers understand central bank responsibility. His 1957 book A Theory of the Consumption Function introduced the permanent income hypothesis, challenging Keynesian models of consumer behavior. These contributions are widely taught across mainstream economics programs regardless of ideological orientation.
Beyond technical economics, Friedman was a prominent public advocate. His 1962 book Capitalism and Freedom and the later popular work Free to Choose (1980, co-authored with his wife Rose Friedman) argued that economic and political freedom are mutually reinforcing, and that government intervention typically produces unintended harms. He advocated for a negative income tax as an alternative to means-tested welfare programs, school vouchers, the abolition of occupational licensing, the legalization of drugs, and the elimination of military conscription. His influence on Republican and conservative economic thinking in the United States, and on the policy direction of governments including those of Ronald Reagan in the United States and Margaret Thatcher in the United Kingdom, is broadly documented.
The extent to which Friedman's policy recommendations-as distinct from his technical economics-are validated by evidence is a matter of ongoing scholarly and political debate. His advisory role during the Pinochet government in Chile in the 1970s attracted lasting controversy. His views on the Civil Rights Act of 1964, which he opposed on libertarian grounds as an infringement on freedom of contract, have been examined from multiple political perspectives; see Civil Rights Act of 1964 - Libertarian Viewpoint.
There is broad consensus among macroeconomists that Friedman and Schwartz's monetary explanation for the severity of the Great Depression represented a durable contribution to the field, and that money supply growth is an important factor in long-run inflation, though the precise mechanisms and magnitudes remain subjects of ongoing research and debate. This consensus does not extend to the full suite of Friedman's policy positions, which remain subjects of active debate. See milton-friedman-monetarism-consensus.
Conservative and free-market viewpoint: Friedman is regarded as one of the most important economists of the twentieth century and a foundational thinker for market-liberal policy. His work is seen as providing rigorous intellectual grounding for reducing the size and scope of government. See milton-friedman-conservative-american-viewpoint and United States of America — Conservative American Viewpoint.
Libertarian viewpoint: Friedman occupies a complex position in libertarian thought. He is admired for his consistent defense of individual liberty, his opposition to conscription and the drug war, and his critique of state power, though some libertarians consider his support for a negative income tax and a government-managed monetary rule insufficiently radical. See milton-friedman-libertarian-viewpoint.
Keynesian and center-left viewpoint: Economists in the Keynesian tradition acknowledge Friedman's technical contributions while disputing his policy conclusions. Critics argue that his framework understates the stabilizing role of fiscal policy and that deregulation and monetarist prescriptions produced distributional harms. See milton-friedman-keynesian-viewpoint.
Left and socialist viewpoint: Critics from the left argue that Friedman's framework served as intellectual cover for policies that increased inequality, weakened labor power, and prioritized capital over workers. His association with the Pinochet government is cited as evidence that free-market doctrine was compatible with, or actively enabled, authoritarian politics. See milton-friedman-left-viewpoint.
Chile advisory controversy: Friedman's visits to Chile in 1975 and his correspondence with Augusto Pinochet, whose government had come to power through a coup and was engaged in human rights abuses, generated sustained public criticism and a debate over the relationship between free-market economics and political repression. See milton-friedman-chile-controversy.
Civil Rights Act opposition controversy: Friedman's stated opposition to the Civil Rights Act of 1964 on freedom-of-contract grounds attracted criticism from civil rights advocates and prompted debate about whether libertarian economic reasoning is compatible with racial equality.
