Capital does not maintain laborers during the progress of their work, as is erroneously taught. Laborers are maintained by their labor, the man who produces, in whole or in part, anything that will exchange for articles of maintenance, virtually producing that maintenance. Capital, therefore, does not limit industry, as is erroneously taught, the only limit to industry being the access to natural material. But capital may limit the form of industry and the productiveness of industry, by limiting the use of tools and the division of labor. That capital may limit the form of industry is clear. Without the factory, there could be no factory operatives; without the sewing machine, no machine sewing; without the plow, no plowman; and without a great capital engaged in exchange, industry could not take the many special forms which are concerned with exchanges. It is also as clear that the want of tools must greatly limit the productiveness of industry. If the farmer must use the spade because he has not capital enough for a plow, the sickle instead of the reaping machine, the flail instead of the thresher; if the machinist must rely upon the chisel for cutting iron; the weaver on the hand loom, and so on, the productiveness of industry cannot be a tithe of what it is when aided by capital in the shape of the best tools now in use. Nor could the division of labor go further than the very rudest and almost imperceptible beginnings, nor the exchanges which make it possible extend beyond the nearest neighbors, unless a portion of the things produced were constantly kept in stock or in transit. Even the pursuits of hunting, fishing, gathering nuts, and making weapons could not be specialized so that an individual could devote himself to any one, unless some part of what was procured by each was reserved from immediate consumption, so that he who devoted himself to the procurement of things of one kind could obtain the others as he wanted them, and could make the good luck of one day supply the shortcomings of the next. While to permit the minute subdivision of labor that is characteristic of, and necessary to, high civilization, a great amount of wealth of all descriptions must be constantly kept in stock or in transit. To enable the resident of a civilized community to exchange his labor at option with the labor of those around him and with the labor of men in the most remote parts of the globe, there must be stocks of goods in warehouses, in stores, in the holds of ships, and in railway cars, just as to enable the denizen of a great city to draw at will a cupful of water, there must be thousands of millions of gallons stored in reservoirs and moving through miles of pipe.
