I am a left communist, just a certain tendency of left communism (Bordigism).
I agree with a lot of left communist ideas, such as being against national liberation movements, agreeing with Gorter's open letter to Lenin, disagreeing with popular frontism and the united frontism of Trotsky, being against participating in bourgeois parliaments and trade unions, etc.
That is an interesting point about sell of labor power that I did not think about!
I would say that too many characteristics of capitalism were missing for the society to be genuinely "state capitalist".
As for the whole bourgeoisie thing, Ticktin addresses this in the case of the Stalinist period of the Soviet Union. A class is a collectivity, and Stalin was an individual. Post-Stalin, though, you could argue that they were a class, but I would say they were a coordinator class like DNZ would argue.
I wouldn't say that post-Stalin it was state capitalist. It was closer to it, but some essential things such as the selling of labor power was absent.
Sorry, I am really busy. Work is giving me a hell of a lot of hours.
Anyway, I like your responses. As for the "world competition" thing that is inescapable until world revolution and would exist until the lower stage of communism can be established and the world revolution achieves success. While I agree that it is "capitalist" it does not in itself show state capitalism existing.
As for the "profit" thing Ticktin was talking of the Soviet Union in a general and abstract sense, not at a specific time. To be continued...
