Organizations, like the people who run them, are flawed.
Never forget that. No matter how shining the reputation or noble the achievements, the organization is not without flaws.
All organizations need regular doses of humility blended with serious introspection. [For recent examples, look at the FBI, the CIA, Disney, The New York Times, and Harvard. Excellent in so many ways and yet capable of making mind-numbing blunders.]
David Halberstam's "The Best and the Brightest" should be assigned reading in high schools. Tuck it in with the classics by Orwell and Huxley.*
*That is unlikely to happen. The high schools are flawed.
