Social democracy

Social democracy accepts markets and parliamentary democracy while insisting the state must decommodify the essentials — health, education, security in old age — and bargain collectively on behalf of labour. It is reformist by conviction rather than by compromise.

Its founding argument was revisionism. Bernstein's Evolutionary Socialism (1899) observed that capitalism was not collapsing as Marx predicted, that workers were winning real gains through the ballot and the union, and that the movement should revise its practice to match — pursuing socialism as a direction of travel rather than an apocalyptic break. Crosland's The Future of Socialism (1956) went further, arguing that ownership had ceased to be the decisive question and that equality could be pursued through taxation, growth, and public services.

It is arguably the most successful political tradition of the twentieth century in the democracies. The Nordic model — Sweden's long Social Democratic governments above all — paired a dynamic market economy with universal welfare, high taxation, and centralized wage bargaining, achieving among the lowest inequality and highest living standards on record. Postwar Western Europe's welfare states are largely its work.

Its defining wager is that class conflict can be institutionalized rather than won: that a durable, negotiated settlement between capital and labour, brokered by the state, is achievable and worth defending. This is what separates it from democratic socialism (which still wants to transform ownership) and from Leninism (which wants to abolish the bargain).

Since the 1980s its critics have come from two sides. Globalization and capital mobility weakened labour's bargaining power and strained the tax base, prompting a 'Third Way' accommodation with markets that the left calls capitulation; meanwhile the right argues its welfare commitments outrun what growth can fund.

It is often blurred together with democratic socialism, but the difference is real and load-bearing: social democracy has made its peace with capitalism and seeks to tame it permanently, rather than to replace it.
