Socialist economy cannot reject the huge advantages of the world division of labor: on the contrary, it will carry it to the highest development. But in practise, it is not a question of the future socialist society, with an established internal equilibrium, but of the given technically and culturally backward country which in the interests of industrialisation and collectivization is forced to export as much as possible in order to import as much as possible.
Leon TrotskyTranscending class distinctions, the speaker [Stalin] portrays the relation between the bourgeoisie and the proletariat as a mere division of labor. The workers and soldiers achieve the revolution, Guchkov and Miliukov "fortify" it.[...] This superintendent's approach to the historical process is exactly characteristic of the leaders of Menshevism, this handing out of instructions to various classes and then patronizingly criticizing their fulfillment.
Leon TrotskyIn Stalin each [Soviet bureaucrat] easily finds himself. But Stalin also finds in each one a small part of his own spirit. Stalin is the personification of the bureaucracy. That is the substance of his political personality.
