True Communism has never been tried

Western leftists conviniently forget the 3year period of War Communism in Russia, a brief experiment with "True Communism" that failed so hard, Lenin started NEP(new economic program, semi-centralised market economy) to allow USSR to survive.

On May 8, 1929, through an agreement signed with Kahn by President of Amtorg Saul G. Bron, the Soviet government contracted the Albert Kahn firm to design the Stalingrad Tractor Plant, the first tractor plant in the USSR. On January 9, 1930, a second contract with Kahn was signed for his firm to become consulting architects for all industrial construction in the Soviet Union.[9]

Under these contracts, during 1929–1932, Kahn's firm operated from its headquarters in Detroit and the newly established design bureau in Moscow to train and supervise Soviet architects and engineers. The bureau Gosproektstroi was headed by Albert Kahn's younger brother, Moritz Kahn, and 25 Kahn Associatese staff were involved in Moscow in this project. They trained more than 4,000 Soviet architects and engineers; and designed 521 plants and factories[3] under the first five-year plan.[9][10]
