The cultural revolution began by lynching all the teachers and kicking the bureaucrats out of the cities. Stalin did much of the same. It was a horrible strategy which is why they came up with the new ones.

I can think of many nasty things that Stalin did, but I don't recall anything even remotely similar to "lynching all the teachers and kicking the bureaucrats out of the cities". In fact, teacher was probably one of the most respected occupations throughout the Soviet period.
