Why did Stalin immediately begin to change agriculture and industry after succeeding Lenin in 1924?

Answer 1

Significant changes weren't fully implemented until 1929 with the end of NEP (New Economic Policy). When Lenin died, Stalin continued this policy while instituting what is called Collectivization. It was a manner with which to collectively bring all aspects of life under the control of the government to ensure stability and efficiency of all aspects of agriculture and industry. Industry was already highly controlled by the Bolshevik government since they always stood for the workers, but they viewed the peasants, profiting off their farms while the workers starved as being unjust. They therefore collectivized the farmland and turned the farms into agricultural factories. All of Soviet society was made to run like a machine (in theory). When considering Lenin and Stalin, changes can be seen in the institution of NEP in the first place as Lenin had begun to decline in health and Stalin capitalized on his weakened state by assuming the prime role of leadership in the party... Stalin's changes to agriculture and industry have nothing to do with Lenin, merely another example of Stalin manipulated the situation to meet his own needs.
