"Under the natural course of things each citizen tends towards his fittest function. Those who are competent to the kind of work they undertake, succeed, and, in the average of cases, are advanced in proportion to their efficiency; while the incompetent, society soon finds out, ceases to employ, forces to try something easier, and eventually turns to use."

Unlike private enterprise which quickly modifies its actions to meet emergencies - unlike the shopkeeper who promptly finds the wherewith to satisfy a sudden demand - unlike the railway company which doubles its trains to carry a special influx of passengers; the law-made instrumentality lumbers on under all varieties of circumstances at its habitual rate. By its very nature it is fitted only for average requirements, and inevitably fails under unusual requirements.
