What social and political signs of the completion of modernization were observed in the USSR in the 1930s?

The processes of Stalinist modernization are very contradictory. On the one hand, this gave a significant impetus to the development of a number of economic sectors in the Soviet Union, and made it possible to obtain a certain number of benefits for the state. On the other hand, in the course of collectivization, the state for a long time lost the peasants interested in their work, the owner’s vein was lost. At the same time, significant progress was observed in the elimination of illiteracy and education. Housing conditions have improved to some extent. However, people remained to some extent under the pressure of the totalitarian state.
