These dealers naturally buying things when they are cheapest, and storing them up to be brought again into the market when the price has become unusually high; the tendency of their operations is to equalize price, or at least to moderate its inequalities. The prices of things are neither so much depressed at one time, nor so much raised at another, as they would be if speculative dealers did not exist.
Speculators, therefore, have a highly useful office in the economy of society; and (contrary to common opinion) the most useful portion of the class are those who speculate in commodities affected by the vicissitudes of seasons. If there were no corn-dealers, not only would the price of corn be liable to variations much more extreme than at present, but in a deficient season the necessary supplies might not be forthcoming at all. Unless there were speculators in corn, or unless, in default of dealers, the farmers became speculators, the price in a season of abundance would fall without any limit or check, except the wasteful consumption that would invariably follow. That any part of the surplus of one year remains to supply the deficiency of another, is owing either to farmers who withhold corn from the market, or to dealers who buy it when at the cheapest and lay it up in store.
§ 5.Among persons who have not much considered the subject, there is a notion that the gains of speculators are often made by causing an artificial scarcity; that they create a high price by their own purchases, and then profit by it. This may easily be shown to be fallacious. If a corn-dealer makes purchases on speculation, and produces a rise, when there is neither at the time nor afterwards any cause for a rise of price except his own proceedings; he no doubt appears to grow richer as long as his purchases continue, because he is a holder of an article which is quoted at a higher and higher price: but this apparent gain only seems within his reach so long as he does not attempt to realize it. If he has bought, for instance, a million of quarters, and by withholding them
