Practice shows that the US presidents change in 4, max 8 years even if they have orange hair and another pathological liar failed to rig the elections. Socialists, on the other hand, stick to the power until they destroy the country.
Of course, there's always going to be a spectrum of freedom. North Korea and China are both communist states yet the civil freedom and standard of living are very different.

The Soviet Union still had a transformation it needs to go through before it can become a modern state that can quickly react to changes. Right now power is too centralized which makes it difficult to respond to changes demanded by shifting technology and and market changes. Countries like India and China will have the lime light pretty soon while Russia plays catch up with the rest of the world. They're bleeding too much money during this time and at some point will have to spend time recuperating.
