This is not hyperbole; it is fact. The world of business and enterprise must go on; it cannot stop. As it goes on capital must be enlisted, which is another way of saying that speculators must be attracted. The only way that has been devised to attract them is through the medium of certificates of ownership or evidences of debt, called securities. But the business does not end there, for, as we have seen in the previous chapter, the capital of speculators will not take hold unless a market is provided. They want to know where they stand; before they venture upon the troubled waters of new enterprises they must be assured of a public market, a harbor where they can get ashore quickly if storms are brewing. The only plan that the ingenuity of man has thus far devised to meet this emergency is a Stock Exchange. One man, or two, or a hundred cannot make a market, because the immense volume and variety of these securities make it impossible for any unorganized handful of brokers and dealers to determine a fair market price. What is required, and what the man whose capital is wanted insists upon, is an organized body of brokers, speculators, and investors competing keenly, seeking to buy cheap and sell dear, gathering and disseminating all the news, and so sharpening the judgment and stimulating the higgling of buyers and sellers as to bring prices to their legitimate level and give them stability. Ten thousand competitors in this business of bringing prices and values together are of course better than one thousand; a hundred thousand would be better still. The Stock Exchange supplies this want, and will continue to supply it until a better plan is devised.[16] Meantime, since it has grown to its present stature by forms of speculation necessary to the maintenance of enterprise, any serious interruption of the facilities it affords will bring enterprise to a standstill and cause the whole sensitive structure of credit to collapse in terror. Let Professor Seligman explain this matter:
