Now, to return to what would be the true course of things. As the progress of such events is always gradual, industry from its nature being opposed to sudden transits, let us suppose that, without waiting the extreme point, it will have gradually divided itself between A and B, according to the laws of supply and demand; that is to say, according to the laws of justice and usefulness. I do not advance an empty hypothesis when I say, that were it possible that industry should concentrate itself upon a single point, there must, from its nature, arise spontaneously, and in its midst, an irresistible power of decentralization. We will quote the words of a manufacturer to the Chamber of Commerce at Manchester (the figures brought into his demonstration are suppressed): "Formerly we exported goods; this exportation gave way to that of thread for the manufacture of goods; later, instead of thread, we exported machinery for the making of thread; then capital for the construction of machinery; and lastly, workmen and talent, which are the source of capital. All these elements of labor have, one after the other, transferred themselves to other points, where their profits were increased, and where the means of subsistence being less difficult to obtain, life is maintained at a less cost. There are at present to be seen in Prussia, Austria, Saxony, Switzerland, and Italy, immense manufacturing establishments, founded entirely by English capital, worked by English labor, and directed by English talent." We may here perceive, that Nature, or rather Providence, with more wisdom and foresight than the narrow rigid system of the protectionists can suppose, does not permit the concentration of labor, the monopoly of advantages, from which they draw their arguments as from an absolute and irremediable fact. It has, by means as simple as they are infallible, provided for dispersion, diffusion, mutual dependence, and simultaneous progress; all of which, your restrictive laws paralyze as much as is in their power, by their tendency towards the isolation of nations. By this means they render much more decided the differences existing in the conditions of production; they check the self-leveling power of industry, prevent fusion of interests, and fence in each nation within its own peculiar advantages and disadvantages. III. To say that by a protective law the conditions of production are equalized, is to disguise an error under false terms. It is not true that an import duty equalizes the conditions of production. These remain after the imposition of the duty just as they were before. The most that the law can do is to equalize the _conditions of sale_. If it should be said that I am playing upon words, I retort the accusation upon my adversaries. It is for them to prove that _production_ and _sale_ are synonymous terms, which if they cannot do, I have a right to accuse them, if not of playing upon words, at least of confounding them.
