Substantially the same proposition is expressed in the commonplace remark that each class envies and emulates the class next above it in the social scale, while it rarely compares itself with those below or with those who are considerably in advance.

That is to say, in other words, our standard of decency in expenditure, as in other ends of emulation, is set by the usage of those next above us in reputability; until, in this way, especially in any community where class distinctions are somewhat vague, all canons of reputability and decency, and all standards of consumption, are traced back by insensible gradations to the usages and habits of thought of the highest social and pecuniary class--the wealthy leisure class.
It is for this class to determine, in general outline, what scheme of Life the community shall accept as decent or honorific; and it is their office by precept and example to set forth this scheme of social salvation in its highest, ideal form.

But the higher leisure class can exercise this quasi-sacerdotal office only under certain material limitations.

The class cannot at discretion effect a sudden revolution or reversal of the popular habits of thought with respect to any of these ceremonial requirements.

It takes time for any change to permeate the mass and change the habitual attitude of the people; and especially it takes time to change the habits of those classes that are socially more remote from the radiant body.
