> This should make everyone even more suspicious of the management consultancies claiming to employ the smartest people in the world.

who thinks they're the smartest? how long have you been in the working world?

they're there to present a veneer of credibility to allow executives to make risky moves or justify ugly choices.

you're a executive in a F500 looking at blowing $200M of shareholder cash on something -- do your due diligence and get someone "smart" to tell you what's what.
