The exploitive relationship is more than the sum of grievances and mutual antagonisms. It is a relationship which can be seen to take distinct forms in different historical contexts, forms which are related to corresponding forms of ownership and State power. The classic exploitive relationship of the Industrial Revolution is depersonalized, in the sense that no lingering obligations of mutuality – of paternalism or deference, or of the interests of ‘the Trade’ – are admitted. There is no whisper of the ‘just’ price, or of a wage justified in relation to social or moral sanctions, as opposed to the operation of free market forces. Antagonism is accepted as intrinsic to the relations of production. Managerial or supervisory functions demand the repression of all attributes except those which further the expropriation of the maximum surplus value from labour. This is the political economy which Marx anatomized in Das Kapital. The worker has become an ‘instrument’, or an entry among other items of cost.
