From the foregoing survey of the growth of conspicuous leisure and consumption, it appears that the utility of both alike for the purposes of reputability lies in the element of waste that is common to both. In the one case it is a waste of time and effort, in the other it is a waste of goods. Both are methods of demonstrating the possession of wealth, and the two are conventionally accepted as equivalents. The choice between them is a question of advertising expediency simply, except so far as it may be affected by other standards of propriety, springing from a different source. On grounds of expediency the preference may be given to the one or the other at different stages of the economic development. The question is, which of the two meth- ods will most effectively reach the persons whose convictions it is desired to affect. Usage has answered this question in different ways under different circumstances.
