BTW there is a parallel discussion going on here:

I certainly don't claim to be an expert in all this - just struggle to see how a bureaucracy defending the interests of "planning" in the form of a planned economy based on the ongoing exploitation of the working class can be described as any kind of "workers" state, even a very "degenerate" one.
If a state can operate against the interests of private capital without it being run in the interests of the workers (let alone run by then directly), then it's hard to see why the particular forms of nationalisation in the USSR were uniquely "reclaimable"
