vonMises proposed socialism cannot work because the state cannot collect all the information needed to make optimal economic decisions, and that it offers no incentives toward optimal economic behavior on the part of the populace. Hayek argued that even if it could, it could not process the information in real-time as efficiently as the distributed processing power of the market. Both critiques were borne out by the experience of the countries that fell under the Bolshevik yoke during the 20th century.
