Naomi Schaefer Riley spoke about her new book in which she argues that teacher tenure is a primary factor in the rapid rise of university tuition costs. She suggested that tenure translates into a "job for life entitlement mentality" among professors. She also made the case that tenure promotes a class system in higher education which leaves teacher's assistants and other low paid contingent faculty teaching a large portion of undergraduate students. She suggested that a thorough review of faculty work roles at American universities was necessary to remedy these problems.
