If the previous socio-economic formations arose and developed spontaneously, then the communist formation is created by people consciously. In the construction of communism, as N. S. Khrushchev said from the rostrum of the XXII Congress, the Leninist party relies on the conscious creativity of the masses. The role of consciousness and activity of the Soviet person in the creation of communist marriage and family relations is great.
