On this head the guiding incentives of the businessman and the material interest of the community at large--not to speak of the selfish interest of the individual workman--are systematically at variance. The cost of production of workmen does not fall on the business concern which employs them, at least not in such definite fashion as to make it appear that the given business concern or businessman has a material interest in the economical consumption of the man-power embodied in this given body of employees. Some slight and exceptional qualification of this statement is to be noted, in those cases where the processes in use are such as to require special training, not to be had except by a working habituation to these processes in the particular industrial plant in question. So far as such special training, to be had only as employees of the given concern, is a necessary part of the workman's equipment for this particular work, so far the given employer bears a share and an interest in the cost of production of the workmen employed; and so far, therefore, the employer has also a pecuniary interest in the economical use of his employees; which usually shows itself in the way of some special precautions being taken to prevent the departure of these workmen so long as there is a clear pecuniary loss involved in replacing them with men who have not yet had the special training required. Evidently this qualifying consideration covers no great proportion of the aggregate man-power consumed in industrial enterprises under business management. And apart from the instances, essentially exceptional, where such a special consideration comes in, the businessmen in charge will, quite excusably as things go, endeavour to consume the man-power of which they dispose in the persons of their employees, not at the rate that would be most economical to the community at large, in view of the cost of their replacement, nor at such a rate as would best suit the taste or the viability of the particular workman, but at such a rate as will yield the largest net pecuniary gain to the employer. There is on record an illustrative, and indeed an illustrious, instance of such cannily gainful consumption of man-power carried out systematically and with consistently profitable effect in one of the staple industries of the country. In this typical, though exceptionally thoroughgoing and lucrative enterprise, the set rule of the management was, to employ none but select workmen, in each respective line of work; to procure such select workmen and retain them by offering wages slightly over the ordinary standard; to work them at the highest pace and pressure attainable with such a picked body; and to discharge them on the first appearance of aging or of failing powers. In the rules of the management was also included the negative proviso that the concern assumed no responsibility for the subsequent fortunes of discharged workmen, in the way of pension, insurance or the like.
