His works, which include Deschooling Society 1971, Towards a History of Need 1978, and Gender 1983, are a critique against contemporary economic development, especially in the Third World. Illich was born in Vienna and has lived in the USA and Latin America. He believes that modern technology and bureaucratic institutions are destroying peasant skills and self-sufficiency and creating a new form of dependency: on experts, professionals, and material goods. True liberation, he believes, can only be achieved by abolishing the institutions on which authority rests, such as schools and hospitals.
