You haven’t explained why socialism was dissolved in the USSR, though, despite gesturing towards your belief that it was an inevitability of the system to do so. This is wrong, though, contemporary analysis shows that the USSR, though slowing down in development, was still positively growing and developing, and was under no real material crisis at the time of its dissolution. It was killed politically. Without understanding the context and underlying causes, you’re just hinting that it’s related to the socialist system itself.

Why then, have the PRC, Cuba, DPRK, Vietnam, and Laos continued their socialist systems? How are they similar, and how are they different? Do you believe their collapse is similarly inevitable as you believe the USSR’s dissolution to have been, or is that unique to the USSR’s conditions?

As for Italy and the cooperative movement, it’s neat, but it isn’t socialism, and is in the context of an imperialist state. If Italy had cooperative ownership as the principle aspect of its economy and had given up on its imperialism, we would have an interesting discussion on socialism vs cooperativism, but that’s not the case. Australia is a capitalist settler-colony and too depends on imperialism.
