But it is otherwise with the superior pecuniary class, with which we are here immediately concerned. For this class also the incentive to diligence and thrift is not absent; but its action is so greatly qualified by the secondary demands of pecuniary emulation, that any inclination in this direction is practically overborne and any incentive to diligence tends to be of no effect. The most imperative of these secondary demands of emulation, as well as the one of widest scope, is the requirement of abstention from productive work. This is true in an especial degree for the barbarian stage of culture. During the predatory culture labour comes to be associated in men's habits of thought with weakness and subjection to a master. It is therefore a mark of inferiority, and therefore comes to be accounted unworthy of man in his best estate. By virtue of this tradition labour is felt to be debasing, and this tradition has never died out. On the contrary, with the advance of social differentiation it has acquired the axiomatic force due to ancient and unquestioned prescription. In order to gain and to hold the esteem of men it is not sufficient merely to possess wealth or power. The wealth or power must be put in evidence, for esteem is awarded only on evidence. And not only does the evidence of wealth serve to impress one's importance on others and to keep their sense of his importance alive and alert, but it is of scarcely less use in building up and preserving one's self-complacency. In all but the lowest stages of culture the normally constituted man is comforted and upheld in his self-respect by "decent surroundings" and by exemption from "menial offices". Enforced departure from his habitual standard of decency, either in the paraphernalia of life or in the kind and amount of his everyday activity, is felt to be a slight upon his human dignity, even apart from all conscious consideration of the approval or disapproval of his fellows.
