All these four classes run into one another. The same man may belong to all at the same time. All are needed. At home a merchant is a mediator to go between the producer and the manufacturer; between both and the consumer. On a large scale he is the mediator who goes between continents, between producing and manufacturing States, between both and consuming countries. The calling is founded in the state of society, as that in a compromise between man's permanent nature and transient condition. So long as there are producers and consumers, there must be distributors. The value of the calling depends on its importance; its usefulness is the measure of its respectability. The most useful calling must be the noblest. If it is difficult, demanding great ability and self-sacrifice, it is yet more noble. A useless calling is disgraceful; one that injures mankind--infamous. Tried by this standard, the producers seem nobler than the distributors; they than the mere consumers. This may not be the popular judgment now, but must one day become so, for mankind is slowly learning to judge by the natural law published by Jesus--that he who would be greatest of all, must be most effectively the servant of all. There are some who do not seem to belong to any of the active classes, who are yet producers, manufacturers, and distributors by their head, more than their hand; men who have fertile heads, producers, manufacturers, and distributors of thought, active in the most creative way. Here, however, the common rule is inverted: the producers are few--men of genius; the manufacturers many--men of talent; the distributors--men of tact, men who remember, and talk with tongue or pen, their name is legion. I will not stop to distribute them into their classes, but return to the merchant.
