Is seems clear that Russia did not fare well in its move from corrupt authoritarian Communism (a tautology if ever there was one) to the kleptocracy which replaced it - often by the hands of the same people. It is just as clear that eastern Europe
did fare well by the fall of the Soviet empire. If Gorbachev had succeeded in dissolving the Soviet Union without having Russia descend into the chaos which followed things might have been better but I find it hard to see how something like that could have been orchestrated. It more or less worked in Eastern Germany due to the efforts (financially and socially) of Western Germany. The way this was handled in Russia was scandalous and led the country from one failed economic system into another failing one with the oligarchs and their cronies taking the place of the Party. Which country could have been the 'Germany' for Russia? Who could have dissolved the inefficient state conglomerates like Treuhandanstalt [1] did in Eastern Germany, who would have covered the financial losses?
