on a level with that of other people, as he must have had the profit of a manufacturer on the one part, so he must have had that of a shopkeeper upon the other. Let us suppose, for example, that in the particular town where he lived, ten per cent was the ordinary profit both of manufacturing and shopkeeping stock; he must in this case have charged upon every piece of his own goods which he sold in his shop, a profit of twenty per cent. When he carried them from his workhouse to his shop, he must have valued them at the price for which he could have sold them to a dealer or shopkeeper, who would have bought them by wholesale. If he valued them lower, he lost a part of the profit of his manufacturing capital. When again he sold them from his shop, unless he got the same price at which a shopkeeper would have sold them, he lost a part of the profit of his shopkeeping capital. Though he might appear, therefore, to make a double profit upon the same piece of goods, yet as these goods made successively a part of two distinct capitals, he made but a single profit upon the whole capital employed about them; and if he made less than his profit, he was a loser, or did not employ his whole capital with the same advantage as the greater part of his neighbours.

What the manufacturer was prohibited to do, the farmer was in some measure enjoined to do; to divide his capital between two different employments; to keep one part of it in his granaries and stack yard, for supplying the occasional demands of the market; and to employ the other in the cultivation of his land. But as he could not afford to employ the latter for less than the ordinary profits of farming stock, so he could as little afford to employ the former for less than the ordinary profits of mercantile stock. Whether the stock which really carried on the business of the corn merchant belonged to the person who was called a farmer, or to the person who was called a corn merchant, an equal profit was in both cases requisite in order to indemnify its owner for employing it in this manner; in order to put his business upon a level with other trades, and in order to hinder him from having an interest to change it as soon as possible for some other. The farmer, therefore, who was thus forced to exercise the trade of a corn merchant, could not afford to sell his corn cheaper than any other corn merchant would have been obliged to do in the case of a free competition.

The dealer who can employ his whole stock in one single branch of business has an advantage of the same kind with the workman who can employ his whole labour in one single operation. As the latter acquires a dexterity which enables him, with the same two hands, to perform a much greater quantity of work; so the former acquires so easy and ready a method of transacting his business, of buying and disposing of his goods, that with the same capital he can transact a much greater quantity of business. As the one can commonly afford his work a good deal cheaper, so the other can commonly afford his goods somewhat cheaper than if his stock and attention were both employed about a greater variety of objects. The greater part of manufacturers could not afford to retail their own goods so cheap as a vigilant and active shopkeeper, whose sole business it was to buy them at wholesale and to retail them again. The greater part of farmers could still less afford to retail their own corn, to supply the inhabitants of a town, at perhaps four or five miles distance from the greater part of them, so cheap as a vigilant and active corn merchant, whose sole business it was to purchase corn by wholesale, to collect it into a great magazine, and to retail it again.

The law which prohibited the manufacturer from exercising the trade of a shopkeeper endeavoured to force this division in the employment of stock to go on faster than it might otherwise have done. The law which obliged the farmer to exercise the trade of a corn merchant endeavoured to hinder it from going on so fast. Both laws were evident violations of natural liberty, and therefore unjust; and they were both, too, as impolitic as they were unjust. It is the interest of every society that things of this kind should never either be forced or obstructed. The man who employs either his labour or his stock in a greater variety of ways than his situation renders necessary can never hurt his neighbour by underselling him. He may hurt himself, and he generally does so. Jack of all trades will never be rich, says the proverb. But the law ought always to trust people with the care of their own interest, as in their local situations they must generally be able to judge better of it than the legislator can do. The law, however, which obliged the farmer to exercise the trade of a corn merchant was by far the most pernicious of the two.
