What does “liberal” mean here?

A label is a local dialect. Each cell states the normal center of gravity, not a membership test.

LabelUnited StatesUnited KingdomContinental EuropeLatin AmericaAcademic / historical
LiberalCenter-left: civil rights, regulated markets, social insurance; U.S. Democratic mainstreamOften centrist or center-left; Liberal Democrats combine social liberalism and regulated marketsUsually constitutional, pro-European, and market-friendly; may sit center-left or center-rightOften means pro-market constitutional liberal, contrasted with socialist or conservative traditionsA family centered on justified authority, individual liberty, rights, and legal equality
Classical liberalLimited government, private property, free exchange; e.g. many Cato-style positionsNineteenth-century liberal lineage; some modern free-market liberalsOrdoliberal, liberal-conservative, or economic-liberal currents depending on countryMarket-liberal reformers; the label can distinguish them from U.S.-style social liberalsLocke, Smith, Constant, Tocqueville, and Mill, with major internal differences
LibertarianStrong presumption against coercion; Libertarian Party is the named party exampleSmaller current spanning economic and civil-liberty radicalismOften a small classical-liberal or anarchist current; translation variesCan mean market anarchist, minarchist, or civil-libertarian depending on movementA family grounding politics in self-ownership, rights, nonaggression, or strong liberty presumptions
NeoliberalUsually an external label for market-oriented technocracy, deregulation, trade, and fiscal disciplineOften linked to Thatcher-era reform, though supporters rarely use the label consistentlyHistorically includes 1930s efforts to renew liberalism; modern use often means EU-compatible market reformStrongly associated with 1980s–1990s stabilization, privatization, and Washington Consensus reformsThree usages: 1938 renewal project, a policy program, and a broad critical epithet
ConservativeTradition, order, markets, national defense; the coalition includes libertarian and populist wingsTory tradition mixes institutions, nation, property, and pragmatic welfare-state stewardshipChristian democracy, liberal conservatism, or national conservatism are distinct familiesMay mean market reform plus social order, or older oligarchic/clerical traditionsA disposition toward inherited institutions, not one universal economic program
Social democratLeft-liberal reformer favoring unions, universal benefits, and regulated private marketsLabour's reformist tradition, distinct from revolutionary socialismMajor center-left family: capitalist production plus welfare state and bargaining institutionsDemocratic left combining elections, labor rights, and redistributionHistorically revised socialism toward parliamentary reform; today usually retains mixed-market production

The master matrix: eight ideologies, ten tests

Systems answer who owns capital. Ideologies answer what political authority should do. That is why a liberal, conservative, or socialist movement can operate inside more than one economic arrangement.

What's the difference between a liberal and a libertarian?

Short answer: Both descend from a tradition of individual rights, constitutional government, toleration, and legal equality. Modern U.S. liberals permit a broader state to secure fair opportunity, social insurance, and effective citizenship. Libertarians put a stronger presumption against coercion and redistribution, usually limiting government to rights protection or arguing for voluntary alternatives.
Split questionModern U.S. liberalLibertarian
What may government do beyond protecting rights?Supply education, health insurance, income security, infrastructure, environmental protection, and antidiscrimination enforcementOnly functions tightly justified by rights protection; some libertarians accept a minimal safety net, others do not
May taxes change distribution?Yes: progressive taxation can secure fair opportunity and insure social riskGenerally no: holdings and voluntary transfer constrain redistribution; views differ on rectification and land
What is liberty?Both noninterference and effective capacity to participate as an equal citizenPrimarily freedom from coercion; positive goals do not automatically create claims on others

“Neoliberal”: the word, the program, and the epithet

1938: renewal project

The Colloque Walter Lippmann in Paris debated how liberalism should answer monopoly, mass democracy, depression, and totalitarian planning. Its participants did not share one modern program.

1989: policy list

John Williamson used “Washington Consensus” for ten reform areas he thought Washington institutions broadly supported for crisis-hit Latin America. The list below is narrower than later uses.

1990s+: critical epithet

Writers expanded “neoliberal” to cover globalization, austerity, privatization, technocracy, financialization, or market reasoning itself. Ask for the policy, institution, time, and author.

Williamson's 1989/1990 reform areaWhat it meantNot the caricature
1. Fiscal disciplineAvoid large, sustained deficits that drive inflation or payments crisesNot zero public spending
2. Public-expenditure prioritiesShift from generalized subsidies toward basic health, education, and infrastructureNot abolish the state
3. Tax reformBroaden the base and use moderate marginal ratesNot simply cut every tax
4. Interest ratesMarket-determined rates, with positive real ratesNot permanently high rates
5. Competitive exchange rateA rate consistent with export growth and external balanceNot a single mandated exchange regime
6. Trade liberalizationReplace quantitative barriers and reduce protection on a scheduleNot instant exposure without transition
7. Inward foreign investmentRemove barriers to foreign direct investmentWilliamson did not list full capital-account liberalization
8. PrivatizationSell state enterprises where private operation can workNot privatize natural monopolies without rules
9. DeregulationRemove entry/exit barriers while retaining safety, environmental, and prudential rulesNot no regulation
10. Property rightsMake secure rights available, including to informal firmsNot privilege incumbents

Common mistakes

Liberal is not a universal left label

In U.S. speech it usually means center-left. In Europe and Latin America it often signals constitutional and market liberalism. Translate before arguing.

Libertarian is not conservative

They overlap on some markets. Drug law, surveillance, immigration, war, speech, and sexual autonomy expose the split.

Neoliberal does not mean new liberal

The 1938 renewal project, Williamson's ten reform areas, and today's catch-all epithet are three different usages.

Classical liberal is not conservative

Classical liberalism judges inherited institutions by liberty and general law; conservatism grants inheritance and social continuity independent weight. Mises's Liberalism and Bastiat's The Law state the classical case directly.

Social democracy is not democratic socialism

The practical dividing question is ownership: redistribute income from mostly private production, or democratize productive ownership itself?

Fascist economics was not laissez-faire

Private titles survived, but independent unions, entry, investment, trade, and production were subordinated to the state. See the corporatism column in the systems sheet.

One left-right axis loses information

Economic control, civil liberty, national identity, institutional trust, and foreign policy do not move as one bundle. Two-axis charts help, but every chosen axis also hides dimensions.
