The first of these propositions is, that industry is limited by capital. To employ labor in a manufacture is to invest capital in the manufacture. This implies that industry can not be employed to any greater extent than there is capital to invest. The proposition, indeed, must be assented to as soon as it is distinctly apprehended. The expression “applying capital” is of course metaphorical: what is really applied is labor; capital being an indispensable condition. The food of laborers and the materials of production have no productive power; but labor can not exert its productive power unless provided with them. There can be no more industry than is supplied with materials to work up and food to eat. Self-evident as the thing is, it is often forgotten that the people of a country are maintained and have their wants supplied, not by the produce of present labor, but of past. Therefore, as capital increases, more labor can be employed. When the Pittsburg rioters, in 1877, destroyed property, or the product of past labor, they did not realize then that that property might, but now could never again, be employed for productive purposes, and thereby support laborers. They consume what has been produced, not what is about to be produced. Now, of what has been produced, a part only is allotted to the support of productive labor; and there will not and can not be more of that labor than the portion so allotted (which is the capital of the country) can feed, and provide with the materials and instruments of production. Because industry is limited by capital, we are not, however, to infer that it always reaches that limit. There may not be as many laborers obtainable as the capital would maintain and employ. This has been known to occur in new colonies, where capital has sometimes perished uselessly for want of labor. In the farming districts of our Middle and Western States, in harvest-time, crops have been often of late years ruined because farm-hands could not be obtained. In earlier days, President John Adams was unable to hire a man in Washington to cut wood in the surrounding forests with which to warm the White House. The unproductive consumption of productive laborers, the whole of which is now supplied by capital, might cease, or be postponed, until the produce came in; and additional productive laborers might be maintained with the amount.
