Imho this is an emergent property from the fact that most folks don't understand what they're doing. If they did, then every time Mr Dilbert pointy head dude comes up with some nonsense process, they'd explain why it isn't beneficial. Instead most of the time everyone nods. Lawyers don't have crazy people telling them how to write contracts. Doctors don't have people telling them how to saw off legs. Teachers kind of do have dumb people telling them how to teach though.
