The author interrogates the societal/educational justification for business schools, and looks at teaching "case studies".

"Before Enron’s fraud was exposed, its business model was presented in admiring terms by at least five H.B.S. case studies. More damning still, the strategies that later led to its collapse — its asset-light model, its trading platform — were portrayed as innovations. Questions about deregulated energy markets, revolving-door oversight and opaque accounting went unasked."
