In most hierarchies, supercompetence is more objectionable than incompetence.
In a hierarchy, every employee tends to rise to his level of incompetence.
Nobody can be perfect unless he admits his faults, but if he has faults how can he be perfect?
The incompetent with nothing to do can still make a mess of it.
In a hierarchy every employee tends to rise to his level of incompetence ... in time every post tends to be occupied by an employee who is incompetent to carry out its duties ... Work is accomplished by those employees who have not yet reached their level of incompetence.
Many an optimist has become rich simply by buying out a pessimist.
