The Czechoslovak Socialist Republic was a socialist republic from the communist coup of 1948 until the Velvet Revolution of 1989. 95% of all privately owned companies were nationalized. 95% of farms were nationalized. No one could own more than 50 hectares of land. Collectivization worked for some but not others. Larger farms were organized on 3 levels of hierarchy which actually reduced worker participation in decision making. Younger workers left for better jobs in the cities and productivity fell. Reforms in the 1970s saw more investment and improvements began to appear gradually. There were record harvests in the 1980s.
