Somebody: The problem here is that the reforms initiated by social democratic parties have been proven to be more durable than the revolutionary changes initiated by worker's states. Not only that, but the neo-liberal rollback of of reformism has been very much a partial reversal, whereas the changes in the socialist countries have been more thorough. So, why shouldn't workers support the traditional social democratic (now social liberal, if you like) parties and institutions?
^^^^^ CB: And worse, masses of workers support right wing parties and electoral movements , like the Tea Party.
