I think Smartest Guys in the Room was an interesting read that touched on Mckinsey/consultants/Skilling. Besides the fact that some of these guys are cocky, etc... I realized they are good in the theory, the big picture, analyzing a business etc.. but puting those things to work and into action is difficult. Many of these guys don´t realize the difficulty of execution and the repercusions some of these "beneficial" actions can have. For example, Pearson thought probably the most rational thing to increase shareholder value was to increase prices of meds until the customer couldn´t take it anymore, reduce taxes and push the boundaries. But guess what? That draws attention and might end up destroying value. Skilling also had these big ideas of how he could make so much money trading or using complex structures, they sounded good in paper but the reality was different.
