Although I myself dislike Capitalism and grew up myself in USSR, and agree that USSR did achieve quite a bit of successes in a short period of time, the same can be said about Asian "miracles" of 1970s and 1980s. USSR has never been a Socialist country, the whole purpose of its existence was to sustain the Russian Empire. USSR was Russian Empire, with different decorations,some sprinkles of ideology and not much more to it. All the other Asian "socialist" countries countries you brought are just good old corrupt kingdoms of their leader, or in case of China an Empire in disguise.
