The secondary results of this delusion of increased wealth because of rising prices, are even more important than the primary results. Our grocer, for example, decides to spend this $1,168 for an automobile. This helps the automobile business. Hundreds of similar orders induce the automobile company to enlarge its plant. This means extensive purchases of material and employment of labor. The increased demand resulting from a similar condition of things in all departments of industry produces, if other conditions are favorable, a still further rise in prices; hence at the end of another year the grocer perhaps has another imaginary profit, which he spends in enlarging his residence or buying new furniture, etc. The stock market feels the reflection of all this increased business and higher prices. Yet the whole thing is psychological, and sooner or later our grocer must earn and save, by hard work, economical living and shrewd calculation, the amount he has paid for his automobile or furniture. Again, rising stock prices and rising commodity prices react on each other. If the grocer, in addition to his imaginary profit of $1,168 sees a ten per cent. advance in the prices of various securities which he holds for investment, he is encouraged to still larger expenditures; and likewise if the capitalist notes a ten per cent. advance in the stock market, he perhaps employs additional servants and enlarges his household expenditures so that he buys more groceries. Thus the feeling of confidence and enthusiasm spreads wider and wider like ripples from a stone dropped into a pond. And all of these developments are faithfully reflected by the stock market barometer. The result is that, in a year like 1902 or 1906, the high prices for stocks and the feverish activity of general trade are based, to an entirely unsuspected extent, on a sort of pyramid of mistaken impressions, most of which may be traced, directly or indirectly, to the fact that we measure everything in money and always think of this money-measure as fixed and unchangeable, while in reality our money fluctuates in value just like iron, potatoes, or “Fruit of the Loom.” We are accustomed to figuring the money-value of wheat, but we get a headache when we try to reckon the wheat-value of money. When a fictitious situation like this begins to go to pieces, the stock market, fulfilling its function of barometer, declines first, while general business continues active. Then the “money sharks of Wall Street” get themselves roundly cursed by the public and there is a widespread desire to wipe them off the earth in summary fashion. The stock market never finds itself popular unless it is going up; yet its going down undoubtedly does far more to promote the country’s welfare in the long run, for it serves to temper the crash which must eventually come in general business circles and to forewarn us of trouble ahead so that we may prepare for it.
