There was no dictatorship of the proletariat. Trotsky prevented labor unions from going on strike. War communism was forcing workers to labor as slaves. The new economic policy sent managers bourgeois back to run the factories.
It was a top down dictatorship. Not a bottom up dictatorship of the proletariat. It was supposed to be all the power to the soviets. The soviets ended up being a tool for the politburo.
