In further qualification it is to be noted that the leisure class of today is recruited from those who have been successful in a pecuniary way, and who, therefore, are presumably endowed with more than an even complement of the predatory traits. Entrance into the leisure class lies through the pecuniary employments, and these employments, by selection and adaptation, act to admit to the upper levels only those lines of descent that are pecuniarily fit to survive under the predatory test. And so soon as a case of reversion to non-predatory human nature shows itself on these upper levels, it is commonly weeded out and thrown back to the lower pecuniary levels. In order to hold its place in the class, a stock must have the pecuniary temperament; otherwise its fortune would be dissipated and it would presently lose caste. Instances of this kind are sufficiently frequent. The constituency of the leisure class is kept up by a continual selective process, whereby the individuals and lines of descent that are eminently fitted for an aggressive pecuniary competition are withdrawn from the lower classes. In order to reach the upper levels the aspirant must have, not only a fair average complement of the pecuniary aptitudes, but he must have these gifts in such an eminent degree as to overcome very material difficulties that stand in the way of his ascent. Barring accidents, the nouveaux arrivés are a picked body. This process of selective admission has, of course, always been going on; ever since the fashion of pecuniary emulation set in--which is much the same as saying, ever since the institution of a leisure class was first installed. But the precise ground of selection has not always been the same, and the selective process has therefore not always given the same results. In the early barbarian, or predatory stage proper, the test of fitness was prowess, in the naive sense of the word. To gain entrance to the class, the candidate had to be gifted with clannishness, massiveness, ferocity, unscrupulousness, and tenacity of purpose. These were the qualities that counted toward the accumulation and continued tenure of wealth. The economic basis of the leisure class, then as later, was the possession of wealth; but the methods of accumulating wealth, and the gifts required for holding it, have changed in some degree since the early days of the predatory culture. In consequence of the selective process the dominant traits of the early barbarian leisure class were bold aggression, an alert sense of status, and a free resort to fraud. The members of the class held their place by tenure of prowess. In the later barbarian culture society attained settled methods of acquisition and possession under the quasi-peaceable regime of status. Simple aggression and unrestrained violence in great measure gave place to shrewd practice and chicanery, as the best approved method of accumulating wealth.
