Collectivization did not work well. There was a famine 1932–33, in which millions died. Because farmers were not paid much money, and whatever they grew went to the state, the workers did not try their best. The best farming worked on very small bits of land given to the peasants to grow what they liked. On these pieces of land, farmers could keep what they grew. In 1938 these parts of land were 4% of Soviet farmland. However, they grew 20% of its produce.
