In a neo-Marxist take on the Communist Manifesto urging, 'Workers of the world unite; you have nothing to lose but your chains,' Illich decried what he called 'the commodification' of labour, whereby the value of work is judged only by the amount of money earned by doing it. This puts the horse of creativity and community service behind the cart of capitalist evaluation, turning workers not just into wage slaves, but into slaves of meaningless labour.
