Market Socialists believe you can have socialism without central planning: keep markets for allocating goods and coordinating economic activity, but replace capitalist ownership with worker ownership. The result would be an economy of democratic cooperatives competing in markets—combining the efficiency of decentralized price signals with the justice of worker control.
This strain addresses a key criticism of socialism: the information problem. Central planners can't efficiently allocate resources across a complex economy; markets aggregate dispersed knowledge through prices. Market Socialists accept this insight while rejecting the conclusion that capitalism is therefore necessary. Markets can exist without capitalists.
The vision draws on real examples: the Mondragon cooperatives in Spain employ over 80,000 worker-owners in a sophisticated industrial economy. Worker cooperatives exist in many countries, often outperforming conventional firms on productivity, resilience, and worker satisfaction. Italy's Emilia-Romagna region has a thriving cooperative sector. The model works.
Market Socialists are often culturally progressive and internationalist—they share the cosmopolitan outlook common among educated leftists. They believe globalization could benefit workers if ownership structures changed: the problem isn't trade or technology but who controls and profits from them.
At roughly 1.5% of the population, Market Socialists are a small but intellectually influential strain. They're found in cooperative movements, economics departments exploring alternatives to capitalism, and among entrepreneurs and workers interested in different ownership models. They offer a "realistic utopia"—radical in ambition but grounded in existing examples.
