Here is an interesting quote from Nikita Khruschev back in 1959
First Secretary of the Communist Party of the Soviet Union 1953-1964. Certainly the most colorful Soviet leader, Khrushchev is best remembered for his dramatic, often times boorish gestures and “harebrained schemes” designed to attain maximum
propaganda effect, his enthusiastic belief that Communism would triumph over capitalism, and the fact that he was the only Soviet leader ever to be removed peacefully from office–a direct result of the post-Stalin thaw he had instigated in 1956.
Khrushchev honestly believed in the superiority of Communism, and felt that it was only a matter of time before it would destroy the Capitalist system once and for all. He set bold (and ultimately unattainable) goals of “overtaking the West” in food production, initiating massive programs to put vast tracts of virgin lands in Kazakhstan and Siberia under the plow with the help of thousands
of urban Komsomol volunteers who brought little but their enthusiasm with them to the open steppes. Despite being hailed as an expert on agriculture, Khrushchev miscalculated when, after a trip to Iowa in 1959, he became a huge enthusiast of corn and decided to introduce it to his country, most of which has an unsuitable climate. On the industrial front, Khrushchev relaxed Stalin’s emphasis on military production somewhat, resulting in a wider array of consumer goods and an improved standard of living for ordinary Soviet citizens.
