Any industrial venture which falls short in meeting the pecuniary exigencies of the market declines and yields ground to others that meet them with better effect. Hence shrewd business management is a requisite to success in any industry that is carried on within the scope of the market. Pecuniary failure carries with it industrial failure, whatever may be the cause to which the pecuniary failure is due--whether it be inferiority of the goods produced, lack of salesmanlike tact, popular prejudice, scanty or ill-devised advertising, excessive truthfulness, or what not. In this way industrial results are closely dependent upon the presence of business ability; but the cause of this dependence of industry upon business in a given case is to be sought in the fact that other rival ventures have the backing of shrewd business management, rather than in any help which business management in the aggregate affords to the aggregate industry of the community. Shrewd and farsighted business management is a requisite of survival in the competitive pecuniary struggle in which the several industrial concerns are engaged, because shrewd and farsighted business management abounds and is employed by all the competitors. The ground of survival in the selective process is fitness for pecuniary gain, not fitness for serviceability at large. Pecuniary management is of an emulative character and gives, primarily, relative success only. If the change were equitably distributed, an increase or decrease of the aggregate or average business ability in the community need not immediately affect the industrial efficiency or the material welfare of the community. The like can not be said with respect to the aggregate or average industrial capacity of the men at work. The latter are, on the whole, occupied with production of goods; the business men, on the other hand, are occupied with the acquisition of them. Theoreticians who are given to looking beneath the facts and to contemplating the profounder philosophical meaning of life speak of the function of the undertaker as being the guidance and cooerdination of industrial processes with a view to economies of production. No doubt, the remoter effect of business transactions often is such cooerdination and economy, and, no doubt also, the undertaker has such economy in view and is stimulated to his maneuvers of combination by the knowledge that certain economies of this kind are feasible and will inure to his gain if the proper business arrangements can be effected. But it is practicable to class even this indirect furthering of industry by the undertaker as a permissive guidance only. The men in industry must first create the mechanical possibility of such new and more economical methods and arrangements, before the undertaker sees the chance, makes the necessary business arrangements, and gives directions that the more effective working arrangements be adopted.
