Gorbachev thought that he was going to be able to transition the USSR into a Nordic socialist style state. He was extremely incorrect, because of the complete rejection of Stalin's thinking and development modeling earlier by Khrushchev. He attempted to model his methods after an idealised version of Lenin's, but Lenin's methods developed out of the Revolution, and moreover out of the necessity of the preservation of his own life and political party, things that had long since past by the time of Gorbachev.

So you not only repudiated the further developments of revolutionary government from Lenin to Stalin, you have acknowledged an imperial liberal system as 'true socialism', and you have attempted to use aggressive and sweeping reforms that just tell everyone that you don't have any trust in your system as it is set up, tearing down these developed social and political systems without having tested something in it's place, just slapping on liberal ideology because 'That's what they do in America/Sweden.'

A complete rejection of materialist politics.
