(2) There is the stock of completed commodities on hand and ready for the market. The chairs that are finished and ready for sale in the chair factory are of this character. It is to be observed that the same article may be at one time circulating and at another fixed capital. Thus the chairs just spoken of, while they are in the hands of the manufacturer, or passing through those of the dealers, are circulating capital. It is only when they become _fixed in use_ that their character changes. Fixed capital consists (1) of all tools, implements, and machinery, used in the trades. Here, too, belong all structures of every sort for productive purposes; (2) all beasts of burden and draft; (3) all improvements of land implied in clearing, fencing, draining, fertilizing, terracing, etc.; (4) all mental acquisitions gained by labor and which give man power for productive results. Obviously capital, by whomsoever owned, is an advantage to the laborer. But such capital is useless to the owner unless he can unite it with labor. So, too, the ability to labor is of no benefit to the laborer unless he can employ it in connection with capital. Generally the more capital there is in a community, other things being equal, the better it is for the laborer; and the more laborers there are, other things being equal, the better it is for the capitalist. When a factory burns down it may destroy only a small part of the wealth of the owners, and they may not palpably suffer; but it is very likely to deprive the laborers, who are connected with it, of the means of securing their daily sustenance. There is no natural antagonism of interests between capital and labor, but rather the utmost concord and interdependence. Whatever conflicts arise between the laborers and the capitalists come from the unnatural selfishness and jealousy of the parties concerned.
