In strict accuracy nothing should be included under the head of conspicuous waste but such expenditure as is incurred on the ground of an invidious pecuniary comparison. But in order to bring any given item or element in under this head it is not necessary that it should be recognized as waste in this sense by the person incurring the expenditure. It frequently happens that an element of the standard of living which set out with being primarily wasteful, ends with becoming, in the apprehension of the consumer, a necessary of life; and it may in this way become as indispensable as any other item of the consumer's habitual expenditure. As items which sometimes fall under this head, and are therefore available as illustrations of the manner in which this principle applies, may be cited carpets and tapestries, silver table service, waiter's services, silk hats, starched linen, many articles of jewelry and of dress. The indispensability of these things after the habit and the convention have been formed, however, has little to say in the classification of expenditures as waste or not waste in the technical meaning of the word. The test to which all expenditure must be brought in an attempt to decide that point is the question whether it serves directly to enhance human life on the whole-whether it furthers the life process taken impersonally. For this is the basis of award of the instinct of workmanship, and that instinct is the court of final appeal in any question of economic truth or adequacy. It is a question as to the award rendered by a dispassionate common sense. The question is, therefore, not whether, under the existing circumstances of individual habit and social custom, a given expenditure conduces to the particular consumer's gratification or peace of mind; but whether, aside from acquired tastes and from the canons of usage and conventional decency, its result is a net gain in comfort or in the fullness of life. Customary expenditure must be classed under the head of waste in so far as the custom on which it rests is traceable to the habit of making an invidious pecuniary comparison-in so far as it is conceived that it could not have become customary and prescriptive without the backing of this principle of pecuniary reputability or relative economic success. It is obviously not necessary that a given object of expenditure should be exclusively wasteful in order to come in under the category of conspicuous waste. An article may be useful and wasteful both, and its utility to the consumer may be made up of use and waste in the most varying proportions. Consumable goods, and even productive goods, generally show the two elements in combination, as constituents of their utility; although, in a general way, the element of waste tends to predominate in articles of consumption, while the contrary is true of articles designed for productive use. Even in articles which appear at
