"Competent" people are not valuable and over rated because they will flake out in such jobs when the group holds them responsible for all sorts of things they have no control over. They are the first people who recognize lumits. Their own, their teams and the systems. But people dont want to hear about Limits. They want saviors and messaihs. They want fantasy and magic. So the system runs not optimized for efficiency but illusion of control, for damping of anxieties and fears.
