# Laissez-Faire **Laissez-faire** ("let do" or "let it be") is the economic doctrine holding that governments should minimize intervention in markets, allowing supply and demand to operate without regulation, subsidies, or tariffs — and the vault tracks it because it is the intellectual ancestor of virtually every deregulatory, anti-government, and [[Free Market Fundamentalism]] argument in American politics, from the [[Gilded Age]] through the [[Lochner Era]] through [[Neoliberalism]] to the present. To say "the market will sort it out" is to invoke laissez-faire whether you know it or not, and understanding where the idea came from — and how many times it has been discredited, revived, and rebaptized — is essential to understanding the economic arguments the vault documents. ## The intellectual lineage The phrase originated with the French Physiocrats of the 1750s–1770s, who argued against the mercantilist system of state-directed trade and production. Their slogan — "laissez faire, laissez passer" (let it be done, let it pass) — was a demand that the Crown stop granting monopolies, fixing grain prices, and directing economic activity through regulation. The Physiocrats believed that economic activity followed natural laws and that state interference distorted those laws. [[Adam Smith]] incorporated and extended the Physiocrat critique in *The Wealth of Nations* (1776), arguing that individuals pursuing their own self-interest in competitive markets would produce better outcomes than central planning — the "invisible hand" metaphor that became the doctrine's most durable image. Smith was more nuanced than his later admirers acknowledged: he supported public education, regulation of banking, and progressive taxation, and he viewed monopoly power with deep suspicion. But the version of Smith that entered political discourse was the simplified one — markets good, government bad — and that simplification powered two centuries of policy. ## The American arc The doctrine's American history follows a recurring pattern: ascendancy, crisis, retreat, revival. **The [[Gilded Age]] (1870s–1900s)** was laissez-faire's first full flowering in American policy. Industrialists like Carnegie, Rockefeller, and Morgan operated with minimal regulation, labor had virtually no legal protections, and the Supreme Court developed a jurisprudence of "liberty of contract" that struck down state regulatory laws. The intellectual backing came from Social Darwinism — Herbert Spencer's argument that economic competition was natural selection in action, and that government intervention to protect the weak was an interference with evolutionary progress. **The [[Lochner Era]] (1897–1937)** was the judicial expression of laissez-faire at its most aggressive. In [[Lochner v. New York]] (1905), the Supreme Court struck down a New York law limiting bakers' working hours, holding that the law violated the "liberty of contract" implied by the Fourteenth Amendment's Due Process Clause. The decision inaugurated four decades in which the Court routinely invalidated labor laws, minimum wage statutes, and other regulatory measures as unconstitutional intrusions on economic liberty. The Lochner era is now generally regarded as a cautionary tale about judicial activism in service of economic ideology — but the arguments it enshrined have never entirely disappeared from American jurisprudence. **The [[New Deal]] burial (1933–1970s).** The Great Depression discredited laissez-faire more thoroughly than any intellectual critique could. The market did not self-correct; it collapsed, and only massive government intervention — federal deposit insurance, securities regulation, Social Security, labor protections, Keynesian fiscal stimulus — prevented a complete economic breakdown. The Supreme Court's "switch in time" (1937) and the subsequent appointments of Roosevelt-era justices ended the Lochner era's constitutional obstruction of regulation. For roughly four decades, from the New Deal through the Great Society, the bipartisan consensus in American politics accepted a substantial government role in economic management. **The revival (1970s–present).** Laissez-faire returned under new names. [[Friedrich Hayek]]'s *The Road to Serfdom* (1944) and [[Milton Friedman]]'s *Capitalism and Freedom* (1962) provided the intellectual foundations for a revival that argued the New Deal consensus had produced stagflation, bureaucratic sclerosis, and threats to individual liberty. The [[Austrian School]] provided the philosophical framework (spontaneous order, the knowledge problem, the impossibility of rational central planning); the [[Chicago School]] provided the empirical toolkit (monetarism, rational expectations, the critique of Keynesian fine-tuning). [[Ayn Rand]]'s novels provided the moral narrative — the heroic individual producer oppressed by parasitic government. The political expression came through [[Supply-Side Economics]], [[Deregulation]] of airlines, trucking, telecommunications, and finance in the late 1970s and 1980s, and the broader [[Neoliberalism]] that became the consensus position of both parties from Reagan through Clinton through Obama. The 2008 financial crisis — like the Great Depression before it — demonstrated the consequences of inadequate financial regulation, but unlike the 1930s, it did not produce a durable political realignment away from laissez-faire. The Dodd-Frank Act was partial and has been progressively weakened; the intellectual infrastructure of [[Free Market Fundamentalism]] — the think tanks, the donor networks, the law-school pipelines — survived and adapted. ## The contemporary landscape In the vault's framework, laissez-faire is less a specific policy position than a rhetorical inheritance. When the [[Libertarianism]] movement argues against regulation, when the Federalist Society advances textualist interpretations that constrain the administrative state, when DOGE proposes eliminating agencies, when crypto advocates argue for permissionless finance — they are all drawing on the same wellspring, whether they cite [[Adam Smith]] or [[Friedrich Hayek]] or neither. The doctrine's persistence despite repeated empirical failures is itself a phenomenon the vault documents: the infrastructure of ideas matters more than any single crisis, because the infrastructure outlasts the crisis while the crisis only temporarily discredits the idea. The tension between laissez-faire and the populist right is one of the vault's recurring themes. The MAGA movement's embrace of tariffs, industrial policy, and opposition to free trade represents a genuine break with laissez-faire orthodoxy — but the same movement's hostility to environmental regulation, labor protections, and the administrative state is pure laissez-faire under a different flag. The doctrine has not been abandoned so much as selectively applied: free markets for capital, managed markets for labor and trade. ## See also [[Free Market Fundamentalism]] · [[Neoliberalism]] · [[Libertarianism]] · [[Adam Smith]] · [[Milton Friedman]] · [[Friedrich Hayek]] · [[Ayn Rand]] · [[Austrian School]] · [[Chicago School]] · [[Supply-Side Economics]] · [[Deregulation]] · [[Regulatory Capture]] · [[Gilded Age]] · [[Lochner Era]] · [[Lochner v.
