"Disciplined Minds - A critical look at salaried professionals and the soul-battering system that shapes their lives" by Jeff Schmidt is the most important book written which does a social analysis of the professional worker and of professional training at graduate and professional schools.
Among other things, the book is a brilliant survival guide.
