It frequently happens, that while high wages are given to the workmen in one manufacture, those in another are obliged to content themselves with bare subsistence. The one is in an advancing state, and has therefore a continual demand for new hands; the other is in a declining state, and the superabundance of hands is continually increasing. Those two manufactures may sometimes be in the same town, and sometimes in the same neighbourhood, without being able to lend the least assistance to one another. The statute of apprenticeship may oppose it in the one case, and both that and an exclusive corporation in the other. In many different manufactures, however, the operations are so much alike, that the workmen could easily change trades with one another, if those absurd laws did not hinder them. The arts of weaving plain linen and plain silk, for example, are almost entirely the same. That of weaving plain woollen is somewhat different; but the difference is so insignificant, that either a linen or a silk weaver might become a tolerable workman in a very few days. If any of those three capital manufactures, therefore, were decaying, the workmen might find a resource in one of the other two which was in a more prosperous condition; and their wages would neither rise too high in the thriving, nor sink too low in the decaying manufacture. The linen manufacture, indeed, is in England, by a particular statute, open to every body; but as it is not much cultivated through the greater part of the country, it can afford no general resource to the work men of other decaying manufactures, who, wherever the statute of apprenticeship takes place, have no other choice, but either to come upon the parish, or to work as common labourers; for which, by their habits, they are much worse qualified than for any sort of manufacture that bears any resemblance to their own. They generally, therefore, chuse to come upon the parish. Whatever obstructs the free circulation of labour from one employment to another, obstructs that of stock likewise; the quantity of stock which can be employed in any branch of business depending very much upon that of the labour which can be employed in it. Corporation laws, however, give less obstruction to the free circulation of stock from one place to another, than to that of labour. It is everywhere much easier for a wealthy merchant to obtain the privilege of trading in a town-corporate, than for a poor artificer to obtain that of working in it.
