In this fascinating and controversial collection of essays Ivan Illich, Irving K Zola, John McKnight, Jonathan Caplan and Harley Shaiken challenge the power and mystery of professions. Why do we put so much resource into medicine, education and the law with so little apparent result? Why do we hold the professions in awe and allow them to set up what are in effect monopolies? By analyzing these questions and putting forward radical answers, the authors make an invaluable contribution to the public debate on the power of professions.
