“If a railway or other industry, in launching a new enterprise, had to depend on the chance investors at the time of the issue of the securities, it would be seriously hampered. The mere knowledge that at any moment there will be a ready sale on the Exchange greatly increases the circle of purchasers, many of whom may not intend to be permanent investors. The Stock Exchange aids the investment of capital, as the Produce Exchange aids the production of finished commodities. Business orders and corporate needs are intermittent, because they depend on temporary exigencies; the risks at one end, at all events, are eliminated by the unintermittent, continuous market which regular speculation affords. The Cotton Exchange was the result of the disorganization of the cotton trade after the Civil War; speculation in all other staples has in the same way been the consequence of the efforts of the manufacturer to avert the risks of intermittent and spasmodic fluctuations in the raw material. The result of regular speculation is to steady prices. Speculation tends to equalize demand and supply, and by concentrating in the present the influences of the future it intensifies the normal factors and minimizes the market fluctuation. Speculation so far as it has become the regular occupation of a class, differentiated from other business men for this particular purpose, subserves a useful and in modern times an indispensable function.”[17] Here we have an authority who tells us that speculation in securities, no less than in raw materials, is “an indispensable function” if business is to go ahead. The last census shows that 32½ per cent. of the population of the United States is composed of laboring men, not counting agricultural workers. This large army of men is by no means independent; on the contrary it is strictly dependent on the ability of others to give it employment. Shut down the factories, curtail the operations of railways, close the mines and quarries, stop building and new construction, and in greater or less degree suffering and privation among these large masses must ensue.
