 A faction of the Bolsheviks known as the "Left Communists" criticised Sovnarkom's economic policy as too moderate; they wanted nationalisation of all industry, agriculture, trade, finance, transport, and communication.Lenin believed that this was impractical at that stage, and that the government should only nationalise Russia's large-scale capitalist enterprises, such as the banks, railways, larger landed estates, and larger factories and mines, allowing smaller businesses to operate privately until they grew large enough to be successfully nationalised.Lenin also disagreed with the Left Communists about economic organisation; in June 1918, he argued that centralised economic control of industry was needed, whereas Left Communists wanted each factory to be controlled by its workers, a syndicalist approach that Lenin considered detrimental to the cause of socialism.
