_Wealth defined._—If we look at the objects which men number in speaking of their wealth, we shall soon find the list differing in important particulars from the list of things which they enjoy. All enjoyable things contribute to welfare, but not all are wealth. Some, like the air and the sunshine, if never lacking, cannot be counted, _because no storing against future need is practicable_; but the fan that cools the air and the coal that gives heat are counted when they are stored as means of meeting future wants. If we could not foresee wants of ourselves or of those dependent upon us, we could not gather means of supply for those wants. If we had all wants supplied at a wish or a prayer, we should have no incentive to store. The pampered child whose every wish is met has no clear conception of wealth or its uses. Let him be without a meal, and he seeks provision for the future by an effort to save what is left over from his last meal and by exertion to add to his store in anticipation of want. Thus wants, to be met only by exertion, are the foundation of the universal ideas of wealth, and whatever we have stored as a provision against wants becomes our wealth. If hunger were our only desire, our wealth would include only stores of food, conveniences for storing, means of increasing the store, and means of utilizing the articles to be eaten. Each desire adds to the range of articles which may enter our list of objects of wealth until enumeration is impossible. None of these, however, will be stored as wealth beyond the limits of anticipated use: if so stored, they add nothing to the supposed wealth. An isolated family, able to consume only thirty bushels of potatoes in a season, is not more wealthy from having three hundred bushels stored: the wealth is measured by actual relations to wants not otherwise supplied. Even in a populous city, the three hundred bushels of potatoes become a store of wealth only when other people need them and _are able in turn to meet other wants of the owners_. Indeed, we soon come to estimate any object of wealth according to its power, directly or indirectly, to meet the first want that comes. A cherished memento of friendship may be ever so gratifying, and yet find no place in our account of wealth, because it can serve no purpose in meeting other wants.
