The main difference between present communist theory and its previous expressions is that it has now become impossible to conceive of communism as a society of associated producers. This book is about a revolution (i.e. a historical break, not gradual peaceful evolution) that creates communism – not its preconditions. Wage-labour, work-time as cut off from the rest of our life, money, private property, State agencies as mediators of social life and conflicts, all of these must go, and not just be run by collectives. Social change will take time but will start from Day One: in the very early days, the way the insurgents will treat workplaces, organize street-fighting and feed themselves will determine the future unfolding of events.
