According to Marxism-Leninism the “socialist reconstruction of agriculture,” or collectivization, is a necessary step in the process of building socialism and, subsequently, communism. The communists realize, however, that in a country where the peasantry constitutes the overwhelming majority of the population the process may require some time and they admit that in such cases “the socialist reconstruction of agriculture is, after the seizure of power by the working class, the most difficult task of the revolution.”
Lenin was aware of the danger inherent in collectivization and he was planning it as a gradual process. The communist leaders in Eastern Europe and in China, keeping in mind the catastrophic results of the Soviet collectivization drive in the years 1928–33, were even more convinced that they should proceed slowly, gradually, and carefully, without antagonizing the majority of peasants. They tried, as the Bolsheviks had done during the 1920's, to reduce the power of the “kulaks” (the better-off peasants who were still rather poor by Western standards) and to enlist against them the support of the poor peasants and of the rest of the society. Neither the Bolsheviks in the late 1920's nor the communists in Eastern Europe in the late 1940's and in China in the 1950's could tolerate independent producers who represented a political menace and created economic complications for the administrators and the planners. Moreover, the land reforms, which were introduced by the communists for tactical reasons although regarded by them as a retrogressive step, increased the number of small holdings below the optimum size and destroyed larger farms which had been producing the majority of marketable output. The “class struggle in the countryside” had adverse effects on productivity, even when it was limited to discrimination in taxation, in delivery quotas, in availability of credit and producers' goods, and the administrative pressure and chicanery. In many instances it went, however, far beyond these measures.
