items that conduce directly to one's physical comfort, or even that may be necessary to life and health. That is to say, the conspicuously wasteful honorific expenditure that confers spiritual well-being may become more indispensable than much of that expenditure which ministers to the "lower" wants of physical well-being or sustenance only. It is notoriously just as difficult to recede from a "high” standard of living as it is to lower a standard which is already relatively low; although in the former case the difficulty is a moral one, while in the latter it may involve a material deduction from the physical comforts of life.
But while retrogression is difficult, a fresh advance in conspicuous expenditure is relatively easy; indeed, it takes place almost as a matter of course. In the rare cases where it occurs, a failure to increase one's visible consumption when the means for an increase are at hand is felt in popular apprehension to call for explanation, and unworthy motives of miserliness are imputed to those who fall short in this respect. A prompt response to the stimulus, on the other hand, is accepted as the normal effect. This suggests that the standard of expenditure which commonly guides our efforts is not the average, ordinary expenditure already achieved; it is an ideal of consumption that lies just beyond our reach, or to reach which requires some strain. The motive is emulation—the stimulus of an invidious comparison which prompts us to outdo those with whom we are in the habit of classing ourselves. Substantially the same proposition is expressed in the commonplace remark that each class envies and emulates the class next
