When a single government tries to plan every detail of the economy, it risks gathering so much power that ordinary people's freedom shrinks step by step.

Central economic planning concentrates power and gradually erodes individual liberty.

Hayek compared a planned economy to a classroom where one student decides everything for the rest — what they eat, read, or do. It looks organized at first, but that one student cannot know what everyone else knows together. Hayek feared this excessive control gradually leads to a loss of freedom.

Why it matters The debate over how much the state should intervene still shapes economic policy today.
