With respect to the survival of traits characteristic of the ante-predatory savage culture the case is in some degree different. The sheltered position of the leisure class favors the survival also of these traits; but the exercise of the aptitudes for peace and good-will does not have the affirmative sanction of the code of proprieties. Individuals gifted with a temperament that is reminiscent of the ante-predatory culture are placed at something of an advantage within the leisure class, as compared with similarly gifted individuals outside the class, in that they are not under a pecuniary necessity to thwart these aptitudes that make for a non-competitive life; but such individuals are still exposed to something of a moral constraint which urges them to disregard these inclinations, in that the code of proprieties enjoins upon them habits of life based on the predatory aptitudes. So long as the system of status remains intact, and so long as the leisure class has other lines of non-industrial activity to take to than obvious killing of time in aimless and wasteful fatigation, so long no considerable departure from the leisure-class scheme of reputable life is to be looked for. The occurrence of non-predatory temperament with the class at that stage is to be looked upon as a case of sporadic reversion. But the reputable non-industrial outlets for the human propensity to action presently fail, through the advance of economic development, the disappearance of large game, the decline of war, the obsolescence of proprietary government, and the decay of the priestly office. When this happens, the situation begins to change. Human life must seek expression in one direction if it may not in another; and if the predatory outlet fails, relief is sought elsewhere. As indicated above, the exemption from pecuniary stress has been carried farther in the case of the leisure-class women of the advanced industrial communities than in that of any other considerable group of persons. The women may therefore be expected to show a more pronounced reversion to a non-invidious temperament than the men. But there is also among men of the leisure class a perceptible increase in the range and scope of activities that proceed from aptitudes which are not to be classed as self-regarding, and the end of which is not an invidious distinction. So, for instance, the greater number of men who have to do with industry in the way of pecuniarily managing an enterprise take some interest and some pride in seeing that the work is well done and is industrially effective, and this even apart from the profit which may result from any improvement of this kind. The efforts of commercial clubs and manufacturers' organizations in this direction of non-invidious advancement of industrial efficiency are also well know.
