If one looks at modern society, it is obvious that in order to live, the great majority of people are forced to sell their labour power. All the physical and intellectual capacities existing in human beings, in their personalities, which must be set in motion to produce useful things, can only be used if they are sold in exchange for wages. Labour power is usually perceived as a commodity bought and sold nearly like all others. The existence of exchange and wage-labour seems normal, inevitable. Yet the introduction of wage-labour involved conflict, resistance, and bloodshed. The separation of the worker from the means of production, now an accepted fact of life, took a long time and was accomplished by force.In England, in the Netherlands, in France, from the sixteenth century on, economic and political violence expropriated craftsmen and peasants, repressed indigence and vagrancy, imposed wage-labour on the poor. Between 1930 and 1950, Russia decreed a labour code which included capital punishment in order to organise the transition of millions of peasants to industrial wage-labour in less than a few decades. Seemingly normal facts: that an individual has nothing but his labour power, that he must sell it to a business unit to be able to live, that everything is a commodity, that social relations revolve around market exchange… such facts now taken for granted result from a long, brutal process.By means of its school system and its ideological and political life, contemporary society hides the past and present violence on which this situation rests. It conceals both its origin and the mechanism which enables it to function. Everything appears as a free contract in which the individual, as a seller of labour power, encounters the factory, the shop or the office. The existence of the commodity seems to be an obvious and natural phenomenon, and the periodic major and minor disasters it causes are often regarded as quasi-natural calamities. Goods are destroyed to maintain their prices, existing capacities are left to rot, while elementary needs remain unfulfilled. Yet the main thing that the system hides is not the existence of exploitation or class (that is not too hard to see), nor its horrors (modern society is quite good at turning them into media show). It is not even that the wage labour/capital relationship causes unrest and rebellion (that also is fairly plain to see). The main thing it conceals is that insubordination and revolt could be large and deep enough to do away with this relationship and make another world possible.
