Wealth of Nations

Though all capitals are destined for the maintenance of productive labor only, yet the quantity of that labor which equal capitals are capable of putting into motion, varies extremely according to the diversity of their employment; as does likewise the value which that employment adds to the annual produce of the land and labor of the country.

A capital may be employed in four different ways; either: first, in procuring the rude produce annually required for the use and consumption of the society; or, secondly, in manufacturing and preparing that rude produce for immediate use and consumption; or, thirdly in transporting either the rude or manufactured produce from the places where they abound to those where they are wanted; or, lastly, in dividing particular portions of either into such small parcels as suit the occasional demands of those who want them. In the first way are employed the capitals of all those who undertake improvement or cultivation of lands, mines, or fisheries; in the second, those of all master manufacturers; in the third, those of all wholesale merchants; and in the fourth, those of all retailers. It is difficult to conceive that a capital should be employed in any way which may not be classed under some one or other of those four.

Each of those four methods of employing a capital is essentially necessary, either to the existence or extension of the other three, or to the general conveniency of the society.

Unless a capital was employed in furnishing rude produce to a certain degree of abundance, neither manufactures nor trade of any kind could exist.

Unless a capital was employed in manufacturing that part of the rude produce which requires a good deal of preparation before it can be fit for use and consumption, it either would never be produced, because there could be no demand for it; or if it was produced spontaneously, it would be of no value in exchange, and could add nothing to the wealth of the society.

Unless a capital was employed in transporting either the rude or manufactured produce from the places where it abounds to those where it is wanted, no more of either could be produced than was necessary for the consumption of the neighborhood. The capital of the merchant exchanges the surplus produce of one place for that of another, and thus encourages the industry, and increases the enjoyments of both.

Unless a capital was employed in breaking and dividing certain portions either of the rude or manufactured produce into such small parcels as suit the occasional demands of those who want them, every man would be obliged to purchase a greater quantity of the goods he wanted than his immediate occasions required. If there was no such trade as a butcher, for example, every man would be obliged to purchase a whole ox or a whole sheep at a time. This would generally be inconvenient to the rich, and much more so to the poor. If a poor workman was obliged to purchase a month's or six months' provisions at a time, a great part of the stock which he employs as a capital in the instruments of his trade, or in the furniture of his shop, and which yields him a revenue, he would be forced to place in that part of his stock which is reserved for immediate
