The end of acquisition and accumulation is conventionally held to be the consumption of the goods accumulated--whether it is consumption directly by the owner of the goods or by the household attached to him and for this purpose identified with him in theory. This is at least felt to be the economically legitimate end of acquisition, which alone it is incumbent on the theory to take account of. Such consumption may of course be conceived to serve the consumer's physical wants--his physical comfort--or his so-called higher wants--spiritual, aesthetic, intellectual, or what not; the latter class of wants being served indirectly by an expenditure of goods, after the fashion familiar to all economic readers. But it is only when taken in a sense far removed from its naive meaning that consumption of goods can be said to afford the incentive from which accumulation invariably proceeds. The motive that lies at the root of ownership is emulation; and the same motive of emulation continues active in the further development of the institution to which it has given rise and in the development of all those features of the social structure which this institution of ownership touches. The possession of wealth confers honour; it is an invidious distinction. Nothing equally cogent can be said for the consumption of goods, nor for any other conceivable incentive to acquisition, and especially not for any incentive to accumulation of wealth. It is of course not to be overlooked that in a community where nearly all goods are private property the necessity of earning a livelihood is a powerful and ever present incentive for the poorer members of the community. The need of subsistence and of an increase of physical comfort may for a time be the dominant motive of acquisition for those classes who are habitually employed at manual labour, whose subsistence is on a precarious footing, who possess little and ordinarily accumulate little; but it will appear in the course of the discussion that even in the case of these impecunious classes the predominance of the motive of physical want is not so decided as has sometimes been assumed. On the other hand, so far as regards those members and classes of the community who are chiefly concerned in the accumulation of wealth, the incentive of subsistence or of physical comfort never plays a considerable part. Ownership began and grew into a human institution on grounds unrelated to the subsistence minimum. The dominant incentive was from the outset the invidious distinction attaching to wealth, and, save temporarily and by exception, no other motive has usurped the primacy at any later stage of the development.
