In the sphere of ideas one of the more fruitful results of May 1968 was the spread, in France and elsewhere, of the criticism of the commodity as representing the reduction of useful things to objects of commerce and of social and personal relationships to commercial ones. With commodity production, work ceases to be the creative activity of people producing needed useful things and becomes mere labour turning out articles of commerce for sale on a market. People cease to be related to each other as members of a community, whether democratic or hierarchical, and become mere economic units related to each other only through money as buyers and sellers of some object or other of commerce.
