“If a society has the form of its synthesis determined by the labour relationship in the production process, thus deriving its fundamental order directly from the labour process of man's acting upon nature, then the society is, or has the possibility of being, classless. We have spoken of such societies under Marx's term 'communal modes of production'. Labour is either done collectively by members of a tribe, or if done individually or in groups the workers still know what each one does, and work in agreement. People create their own society as producers. The structure enables us to call them ' societies of production '. The alternative is a form of society based on appropriation .”
