The state talked about in the Manifesto of the Communist Party is a dictatorship of the proletariat, a revolutionary society in which the entirety of the industrial working class literally serves as the foundations of the state
I don't know what are you talking about but just above this post I have provided a quote from manifesto, it is quite explicit in saying that a highly centralized state will take place of capitalism. And no it doesn't says that transitionary phase will have "literally" entirely of proletarian serving in state beuracratic machinery or what else do you mean by foundations of the state? This is just utopian socialism and not marxism.
Because the workers are the state then the means of production are owned by them in such a system.
This makes no sense. Workers are not the state just as capitalist now are not literally state but state serves their interests only which conflicts with the interest of workers in dotp situation simply reverses.
The issue is whether such a society formed in the Soviet Union or other Leninist states, and the answer is an emphatic no.
So? Yes, USSR was not your "weired definition of state". But it was a workers state.
Power was rested solely in Party members and particularly in the politburo.
Which came from workers only and party (compromised of working class) got their input from various workers organizations only like trade unions or does someone really expect that every single day to day matter would be resolved by a nationwide vote. Of course it was a centralized system, a necessity to end the anarchy of production as prevalant in capitalist economy while repressing the class enemy.
And as if power is rested in every voting ctizen in capitalist democracies.
The common worker had less stake in the means of production than they do in a market capitalist society.
Opinion are opinions. Everyone got them.
The Soviet Union was not simply an example of capitalism, it was one of the highest forms of capitalism ever realized.
You don't understand capitalism or socialism then. highest form of capitalism?
No, the collapse of the Soviet Union was the single greatest victory socialism has ever seen.
Given the pathetic state of Communist party all over the world since the collapse of USSR, you are objectively wrong.
Edit : Let me tell you something, as marxist have always said, State exist to opress and until their is state there will be oppression, make no mistake of it. But in the meantime state is too powerful a tool to let it pass and fall in the hand of class enemies, it must be retain by working class to crush and organize the proletarian state to move further along the transitionary phase.
