Brooks and Collins on education

What don't they discuss in this week's Conversation, which is about education?  A wide-ranging and fascinating back-and-forth ensues.  I particularly liked the discussion about costs and the growth in managers at UC ("Soon every faculty member will have a personal senior manager") and the trajectories over 4 years of college in various metrics of students' well-being and progress from the Wabash National Study.  Motivation?  Fuhgeddaboudit!
