Social democracy

• 1. Introduction

  ›

  Social democracy sits in an odd place. It is a broad, centre-left ideology inside the wider socialist movement, yet in modern practice it runs a predominantly capitalist economy. The trick is the welfare state attached to that economy. Policies promote social justice, regulate markets, and push for a more equitable distribution of income.

  Richard T. Ely, writing in 1883 for an American audience, called social democrats "the extreme wing of the socialists". A century and a half later, the United Nations World Happiness Report keeps finding the happiest nations clustered in social democratic countries of Northern Europe. How did an idea once labelled extreme become the quiet middle of Western politics? And what got abandoned along the way?

  The answers run through a German revolutionary who decided Marx needed revising, through a split that turned comrades into Communists and Social Democrats overnight, and through a 1990s reinvention that some critics call neoliberalism wearing a centre-left coat. The questions are about goals: whether to replace capitalism or simply tame it, and what is lost when a movement settles for the second.

• 2. The Reformist Turn

  ›

  Eduard Bernstein decided Marx had gotten the timeline wrong. The German social democratic politician rejected orthodox Marxism's claim that history inevitably progressed toward revolution. Socialism, he argued, should rest on ethical and moral grounds and arrive through gradual legislative reform. He called his approach evolutionary socialism, influenced by the gradualist platform of the Fabian movement in Britain.

  Karl Kautsky was not persuaded. He attacked Bernstein in the book Bernstein und das sozialdemokratische Programm: Eine Antikritik, calling out a confusion between freedom of will and freedom of action. Bernstein's party held the line too, insisting reforms were a means to eventual revolution, not a replacement for it.

  Bernstein paid his respects even while breaking ranks. He called Marx the father of social democracy, then declared it necessary to revise Marx's thought in light of changing conditions. He described socialism as organized liberalism, casting liberalism as the predecessor of socialism. He was an advocate of Kantian socialism and neo-Kantianism, and accepted the Marxist view that socialism's creation is interconnected with capitalism's evolution.

  Bernstein expected a long coexistence of democracy with a mixed economy of public, cooperative, and private enterprises. He supported state ownership only for parts of the economy the state could best manage, rejecting a mass scale of it as too burdensome. Unpopular early on, his views became mainstream after World War I.

• 3. When Comrades Became Communists

  ›

  The Russian Revolution forced a choice. Those who supported the October Revolution renamed themselves Communists. Those who opposed the Bolsheviks kept the Social Democrat label. Both groups technically shared the goal of a society realizing "from each according to his ability, to each according to his need", but the Communists wanted distance from social democracy's association with reformism.

  The German Revolution of 1919 made the rupture physical. Communists wanted to overthrow the German government and build a soviet republic like Russia's. The Social Democrats wanted to preserve it as what became the Weimar Republic. Social democracy shifted from a Marxist revolutionary doctrine into a form of moderate parliamentary socialism.

  The Bolsheviks split from the Second International and built their own Communist International, the Comintern, in 1919. The reformists answered by founding the Labour and Socialist International in 1923. The two competed for leadership of the international socialist and labour movement.

  Under politicians like Carlo Rosselli in Italy, social democrats during the 1920s and 1930s pulled away from orthodox Marxism altogether. They embraced liberal socialism and Keynesianism, appealing to morality rather than any systematic materialist worldview. Joseph Stalin coined the term social fascism for them, and the Communist International declared that capitalist society had entered a Third Period in which proletarian revolution was imminent.

• 4. Taming Capitalism

  ›

  Anthony Crosland announced in 1956 that capitalism was already gone. In The Future of Socialism he wrote that "traditional capitalism has been reformed and modified almost out of existence", and that a new kind of capitalism required a new kind of socialism. He believed these features of reformed managerial capitalism were irreversible.

  Aneurin Bevan disputed the larger claim. The Welshman, Minister of Health in the first post-war Labour government and architect of the National Health Service, argued Britain had a socialist National Health Service standing against the hedonism of a capitalist society. The disagreement marked a movement unsure whether it had already won.

  By the post-World War II period most social democrats in Europe had abandoned their connection to orthodox Marxism. Michael Harrington traced the reason to the Stalinist-era Soviet Union, seen as having usurped Marxism's legacy and distorted it to justify totalitarianism. The Socialist International, at its foundation, denounced the Bolshevik-inspired communist movement for falsely claiming a share in the socialist tradition.

  State ownership in France never carried the weight people imagined. Public ownership never accounted for more than 15-20% of capital formation, dropped to 8% in the 1980s, and fell below 5% in the 1990s. President Francois Mitterrand's government tried to nationalize all French banks in the 1980s, but the European Economic Community opposed it, demanding a free-market economy among members.

• 5. The Third Way

  ›

  Clause IV became the battleground. The Labour Party's open advocacy of state socialism, the modernizers argued, was alienating potential middle-class supporters. Nationalization had been so thoroughly attacked by neoliberal economists that, according to Tony Blair, such policies had become politically unviable by the 1990s.

  The Third Way emerged as the answer, a reconceptualization of social democracy developed in the 1990s to fuse economic liberalism with social democratic economic policies. Bill Clinton's New Democrats and Tony Blair's New Labour embraced it most notably. Some political scientists characterize it as effectively a neoliberal movement rather than a social democratic one.

  Tony Blair insisted he remained a socialist, describing himself as a Christian socialist and a socialist in ethical terms. Figures like Anthony Giddens argued the same, claiming to hold the same values as their anti-Third Way critics. Anti-Third Way social democrats returned the accusation, charging that Giddens was anti-social democratic and anti-socialist in practice.

  The Third Way drew on Eduard Bernstein's legacy directly, described as the neo-revisionism that his Marxist revisionism had laid groundwork for. It also reshaped corporatism. Social corporatism, which began in Norway and Sweden in the 1930s and consolidated in the 1960s and 1970s, evolved into neo-corporatism, which became an important concept of Third Way social democracy.

• 6. Drawing The Line

  ›

  Clause IV was rewritten, not deleted. The New Labour faction led by Tony Blair revised it in the 1990s to affirm a formal commitment to democratic socialism, calling it a modernized form of social democracy. The new text dropped public ownership of industry and praised "the enterprise of the market and the rigour of competition" alongside high quality public services.

  David Schweickart, the American democratic socialist philosopher, draws the cleaner distinction. He defines social democracy as an attempt to strengthen the welfare state and democratic socialism as an alternative economic system to capitalism. His critique holds that capitalism can never be sufficiently humanized, and that suppressing its contradictions only makes them surface elsewhere. Reduce unemployment too far and inflation follows; grant too much job security and labour discipline erodes.

  Democratic socialism, in this framing, represents social democracy before the 1970s, when monetarism and neoliberalism displaced Keynesianism. The social democrats committed to gradually abolishing capitalism merged into democratic socialism. One distinction is that democratic socialism can include revolutionary means, while social democracy proposes representative democracy under the rule of law as the only acceptable form of government.

  In the United States the labels tangle further. Social democracy gets equated with wealthy Western countries, while democratic socialism gets conflated with the pink tide in Latin America, especially Venezuela, or with Soviet-style Marxist-Leninist socialism. Tony Judt described modern American liberalism as representing European social democracy.

• 7. The American Exception

  ›

  The United States never built a major socialist party. Its socialist movement stayed comparatively weak, unlike Western Europe, Australia, and New Zealand. Observers have linked the weakness to the Red Scare, after which any ideology tied to socialism carried social stigma from its association with authoritarian states.

  Slavery left the deeper mark. Its legacy institutionalized profound and enduring racial divisions within the American working class. That working class was stratified along racial lines, producing a segmented labour market with conflicting political priorities. This fragmentation undermined class solidarity and constrained mass support for redistributive policies on taxation, social welfare, and economic equality.

  The pieces of social democracy arrived anyway, under other names. The progressive movement, influenced more by social liberalism than socialism, backed Democratic presidents Woodrow Wilson and Franklin D. Roosevelt, whose New Freedom and New Deal programmes adopted many social democratic policies. Democratic socialism in the United States is now tied to the New Deal, described as its left-wing or socialist tradition.

  The movement found new figures after the 2008 crisis. Bernie Sanders, the most recent democratic socialist to run for President, was backed by the We Need Bernie campaign. The Democratic Socialists of America grew to over 24,000 members by July 2017, its largest since the Communist Party before its destruction in 1956. Zohran Mamdani's victory in the 2025 New York City mayoral election marked the largest win in the 43-year history of the DSA.

• 8. What Was Lost

  ›

  Otto von Bismarck built the first modern welfare state to defeat the socialists. The conservative Chancellor put in place social welfare proposals initially suggested by the Social Democrats, beginning in 1883, to appease the working class and reduce support for socialism. He acted after his Anti-Socialist Laws had failed at the same task. The Social Democrats became the biggest party in parliament by 1912 regardless.

  The achievement looked permanent, then proved conditional. Crosland argued in Socialism Now in 1974 that "much more should have been achieved by a Labour Government in office", concluding that "a move to the Left is needed". It has been argued that post-war social democracy was too confident, that gains thought permanent turned out conditional as the reservoir of capitalist growth dried up.

  The critics from the left say the abandonment was total. Jonas Hinnfors argues that when social democracy gave up Marxism, it gave up socialism and became a liberal capitalist movement, making social democrats similar to the Democratic Party in the United States. Joseph Schumpeter put it earlier, in Capitalism, Socialism and Democracy in 1942: socialists in power "would have to 'administer' capitalism". Irving Kristol called democratic socialism "an inherently unstable compound, a contradiction in terms".

  The economists John Roemer and Pranab Bardhan name the structural catch. Social democracy requires a strong labour movement to sustain heavy redistribution through taxes, and they note that social democracy in Scandinavian countries has declined as the labour movement weakened. The model that tops the World Happiness Report rests on a foundation that is itself eroding.
