We have now examined the various forces which are destroying competition in the production of goods in our factories, and of raw material from our mines; in the transportation of these goods in their various journeys between the producer and the consumer, and in the supply of the especial needs of the dwellers in our cities. It is an old and well-worn adage that "competition is the life of trade"; and if this be true, we shall certainly not expect to find the men who are earning their living by the purchase and sale of goods endeavoring to take away the life of their business by restraining or destroying competition. At first sight it seems as if it would be a difficult matter in any case to destroy competition in trade. The buyer and seller of merchandise has no exclusive control over natural wealth; no mine or necessary channel of transportation is under his direction; nor does he in his trade produce any thing, as does the manufacturer. He only serves the public by acting the part of a reservoir to equalize and facilitate the flow between the consumers and producers; and if necessity requires, the two can deal directly with each other and leave him out altogether. But in dealing with the question of monopolies we must not conclude that the absolute control of supply is at all necessary to the existence of a monopoly. While there are monopolies, as we have seen, which have the keys to some of the necessities of civilized life, there are others which control merely some _easier means_ for their production, carriage, or distribution; and to this latter class belong the principal monopolies in trade. To be sure that this constitutes a monopoly, we have but to turn to the case of the mountain pass mentioned in a former chapter. The use of that particular pass for transporting goods is only an _easier means_ of transportation than the detour to some other pass or by some other route; and the degree of power of the monopoly depends directly on the amount which is saved by the use of its facilities. So with the monopolies in trade. Brokers and jobbers and retail merchants form a channel through which trade is accustomed to pass, and through which it can pass more readily than by any new one. It is to be noted that under modern conditions the power of middle-men has been greatly reduced from what it was formerly. As we have already seen, manufacturing was then carried on only in families and small workshops, and the mines which were worked were principally in the hands of the king. The merchants were the wealthy men of olden time. They controlled largely the transportation facilities of that day; and while, as we have already noted, the commerce which then existed was but a trifle compared with the present, the principal exchange being in local communities, yet the trade in all articles which were imported, and all domestic commerce between points any great distance apart was in the hands of the merchants.
