Entrance to the leisure class lies through the pecuniary employments.
These two classes of employment differ materially in respect of the aptitudes required for each; and the training which they give similarly follows two divergent lines.

The discipline of the pecuniary employments acts to conserve and to cultivate certain of the predatory aptitudes and the predatory animus.

It does this both by educating those individuals and classes who are occupied with these employments and by selectively repressing and eliminating those individuals and lines of descent that are unfit in this respect.

So far as men's habits of thought are shaped by the competitive process of acquisition and tenure; so far as their economic functions are comprised within the range of ownership of wealth as conceived in terms of exchange value, and its management and financiering through a permutation of values; so far their experience in economic life favors the survival and accentuation of the predatory temperament and habits of thought.

Under the modern, peaceable system, it is of course the peaceable range of predatory habits and aptitudes that is chiefly fostered by a life of acquisition.
