The highly complex character of modern business, and by this I mean big business, demands a physical endowment that is commensurate with the high intellectual endowment which has made possible the great industrial establishments that control the business of the world. Such an organization requires diversified talent and as its growth is dependent on continuous existence, it is necessary not only that the general health shall be conserved, but that by continuous medical supervision, following elimination of defectives by preliminary examination before employment, the places of those whom disease or advancing age render inefficient shall be from time to time filled by trained subordinates. To meet these conditions and to preserve the traditions of the business is the problem that every large corporation is confronted with.
The aim of the employer is obviously to select from among those who apply a number who will give promise of developing after employment.
