"The management of Enron, in other words, did exactly what the consultants at McKinsey said that companies ought to do in order to succeed in the modern economy.

But what if Enron failed not in spite of its talent mind-set but because of it? What if smart people are overrated?"
The McKinsey stories and the example of the submarine war in the north Atlantic are fascinating.
