The stated purpose of planning according to the communist party was to enable the people through the party and state institutions to undertake activities that would have been frustrated by a market economy (for example, the rapid expansion of universal education and health care, urban development with mass good quality housing and industrial development of all regions of the country). Nevertheless, markets continued to exist in socialist planned economies. Even after the collectivization of agriculture in the Soviet Union in the 1930s, members of the collective farm and anyone with a private garden plot were free to sell their own produce (farm workers were often paid in kind).
