Personal distinction also seems to go with the assumption of adulthood soon after puberty. Whether this is attained through some special attitude or general ability enchannelled by custom, opportunity, or accident in a particular vocation, makes little difference. Poets, painters, mathematicians, scientists, engineers, traders of distinction, assume the professional attitude and the responsibility of adulthood at an early age. Shelley, Keats, Bryant, Peter Cooper, Thomas Jefferson, Benjamin Franklin, George Eliot, Thomas Edison, Maxwell, Galileo, and countless others of the great, all began young. Nelson went to sea at twelve and commanded a ship at fifteen. His contemporary captains in the American merchant marine were boys of eighteen and nineteen. Much of the work of the world continues to be done by men and women under twenty-five. Prizefighters are old at thirty. It is a favorite doctrine of representative American employers, such as Henry Ford, that workingmen over forty are antiquated, and to be scrapped. Did not the great Osler advise euthanasia for all men over sixty? Nevertheless, the ruling personages in the ruling classes--the captains of industry, the masters of finance, the public officials, the judges, the generals--are progressively older and older now. They are men whose minds had matured and set while their bodies were young, and whose policies derive from the unconscious premise that what was modern and advanced in their youth is necessarily so in their old age. They are the elder statesmen who in their prolonged infancy rule the world.... VI If many of these elder statesmen rule by virtue of distinguished ability and early adulthood, most do by virtue of a privileged position that delays adulthood and prolongs infancy more literally. The locus of this position is the high school and the college, especially the college. Owing to democracy, there has been a diffusion of some of the privileges of this status to the children of the masses. One of its marks is the war against child labor which we have noted, and the progressively later age at which work certificates are granted; another is the advancement, already referred to, of the age of consent and the measures for the protection of girls. Still another, and the most signal, is the increase of the high school population from the 300,000 of 1890 to the 5,000,000 of 1930, and the corresponding growth of the body of college students. Nevertheless the difference between the working young and the young at school remains still the difference between the responsibility of adulthood and the irresponsibility of infancy. The difference increases with the income level. The richer the class, the more likely are the young to be kept in a state of social infancy, the longer is the time delayed when they are permitted to assume the responsibilities of adulthood.
