"The Peter Principle is the principle that "In a Hierarchy Every Employee Tends to Rise to His Level of Incompetence." It holds that in a hierarchy, members are promoted so long as they work competently. Sooner or later they are promoted to a position at which they are no longer competent, and there they remain, being unable to earn further promotions. Therefore, all managers, by definition, must be incompetent." Wikipedia

Those posts would disappear and all the idiots that got their foot in the door because there was no one else to fill the posts would be out on their ears.
