Another deficiency in the business structure growing out of the increasing prosperity of the people was next provided for. When an enterprise became so large as to necessitate several owners for its conduct, the prescribing and defining of the relation of these owners to each other and to the common property became a task of increasing difficulty. So the idea arose of welding the enterprise itself into a separate entity which could do all the things the individual might, and yet exist apart from the individual and independent of his personal dealings and comings and goings. His ownership should be an undivided interest in the whole represented by certificates of stock or bonds, which could pass from him to another without interfering with the enterprise. This was invention No. 6: The Corporation. The law then provided regulations for the creation and conduct of these corporations which compelled them to keep their affairs in such shape that all could ascertain of what each consisted.
When these six organizations had been founded, the machinery for the conduct of the business of a civilized people was almost complete. But still one other want developed: with the multiplication of the corporation tokens of property, it became necessary that there should be some place where the worth of these might be ascertained either by purchase, sale, or loan under the regulation of experts. So there was created a common market-place, to which came all those who had corporation tokens of property to sell and those who desired to purchase them; and the prices these brought were announced to the world and became the measure of the value of the institution they represented. Rules for the regulation of the business of the market-place were gradually formulated, and invention No. 7—the Stock Exchange—came into existence.
