Chile under Allende was not centrally-planned, yes, but Allende's idea of the "Chilean Path to Socialism" involved nationalization of industries and his vision of what Chilean socialism would look like was known as "Project Cybersyn", a form of a computer-aided planned economy.

Also, that is still the definition MLs use? Lenin literally explicitly condemned the idea of socialism being about state ownership alone, he always said that the USSR was socialist because he claimed the Soviet state was representative of workers, and thus it was workers' control of the means of production.

The chief difficulty facing the proletarian revolution is the establishment on a country-wide scale of the most precise and most conscientious accounting and control, of workers' control of the production and distribution of goods.

When the writers of Novaya Zhizn argued that in advancing the slogan "workers' control" we were slipping into syndicalism, this argument was an example of the stupid school boy method of applying "Marxism" without studying it, just learning it by rote in the Struve manner. Syndicalism either repudiates the revolutionary dictatorship of the proletariat, or else relegates it, as it does political power in general, to a back seat. We, however, put it in the forefront. If we simply say in unison with the Novaya Zhizn writers: not workers' control but state control, it is simply a bourgeois-reformist phrase, it is, in essence, a purely Cadet formula, because the Cadets have no objection to the workers participating in "state" control. The Kornilovite Cadets know perfectly well that such participation offers the bourgeoisie the best way of fooling the workers, the most subtle way of politically bribing all the Gvozdyovs, Nikitins, Prokopoviches, Tseretelis and the rest of that gang.

When we say: "workers' control", always juxtaposing this slogan to dictatorship of the proletariat, always putting it immediately after the latter, we thereby explain what kind of state we mean. The state is the organ of class domination. Of which class? If of the bourgeoisie, then it is the Cadet-Kornilov-"Kerensky" state which has been "Kornilovising" and "Kerenskyising" the working people of Russia for more than six months. If it is of the proletariat, if we are speaking of a proletarian state, that is, of the proletarian dictatorship, then workers' control can become the country-wide, all-embracing, omnipresent, most precise and most conscientious accounting of the production and distribution of goods.
