"The progressive role of the Soviet bureaucracy coincides with the period devoted to introducing into the Soviet Union the most important elements of capitalist technique. The rough work of borrowing, imitating, transplanting and grafting, was accomplished on the bases laid down by the revolution. There was, thus far, no question of any new word in the sphere of technique, science or art. It is possible to build gigantic factories according to a ready-made Western pattern by bureaucratic command--although, to be sure, at triple the normal cost. But the farther you go, the more the economy runs into the problem of quality, which slips out of the hands of the bureaucracy like a shadow. The Soviet products are as though branded with the gray label of indifference. Under a nationalized economy, quality demands a democracy of producers and consumers, freedom of criticism and intitiative--conditions incompatible with a totalitarian regime of fear, lies and falttery." ("The Revolution Betrayed", Pathfinder Press, New York, 1972, pp. 275-76)
Remember: Stalinism does not equal socialism. A planned economy does not equal a command economy.
