Leftists do not like all changes. Because power is their underlying motivation Leftists/liberals dislike the power-reducing changes that conservatives favour — such as neo-liberal (pro-market) change. Change of that sort threatens the Leftist’s access to power. We also see the primacy of power in the old Soviet system. We saw there that Leftists who had gained power suddenly became very opposed to change. The desire for change is at its base the desire for one particular sort of change: Putting Leftists in power so that they can reshape society into a mould that feels good to them.
