The previous accumulation of commodities requisite for production must inevitably be large enough to cover necessaries, but need not be more, if the laborer is willing to wait for the additional amount of his wages (the amount of his unproductive consumption) until the completion of the industrial operation. In fact, however, the accumulation must be sufficient to pay the laborer all his wages from week to week, by force of custom (wherever there is any considerable division of labor), and also sufficient to purchase tools and materials. The various elements of capital are materials, instruments, and subsistence, giving “instruments” its wide signification which includes money (the tool of exchange), and other necessary appliances of each special kind of production. In truth, it is only after an abundant capital had already been accumulated that the practice of paying in advance any remuneration of labor beyond a bare subsistence could possibly have arisen: since whatever is so paid is not really applied to production, but to the unproductive consumption of productive laborers, indicating a fund for production sufficiently ample to admit of habitually diverting a part of it to a mere convenience. It will be observed that I have assumed that the laborers are always subsisted from capital:(105) and this is obviously the fact, though the capital need not necessarily be furnished by a person called a capitalist. The peasant does not subsist this year on the produce of this year’s harvest, but on that of the last. The artisan is not living on the proceeds of the work he has in hand, but on those of work previously executed and disposed of. Each is supported by a small capital of his own, which he periodically replaces from the produce of his labor. The large capitalist is, in like manner, maintained from funds provided in advance. § 3. Examination of Cases Illustrative of the Idea of Capital. That which is virtually capital to the individual is or is not capital to the nation, according as the fund which by the supposition he has not dissipated has or has not been dissipated by somebody else. Let the reader consider, in the four following suppositions, whether or not the given capital has wholly dropped out of the circle in the diagram, page 67. In (3) and (4) the wealth is entirely dissipated; as it can not longer be in circle A, it can not, of course, be in circle B.
