Secondly, the dissolution of the USSR was driven instead by numerous complex factors:

1. Liberal reforms that gave the Bourgeoisie power over key industries

2. A firm dedication to planning by hand even as the economy grew more complex and computers too slow to be adapted to the planning mechanisms

3. A huge portion of resources were spent on maintaining millitary parity with the US in order to dissuade US invasion

4. 80% of the combat done in World War II was on the Eastern Front, and 20 million Soviets lost their lives, with no real economic support from the West in rebuilding despite taking the largest cost of war

5. An enclosed, heavily sanctioned economy relied on internal resource gathering, closed off from the world market

Countries like the PRC have taken to heart what happened in the USSR. As an example, the PRC shifted to a more classically Marxist economy, focusing on public ownership of only the large firms and key industries, and relying on markets to develop out of private ownership. This keeps them in touch with the global economy without giving the bourgeoisie control of key industries, and thus the bourgeoisie has no power over the economy or the state.
