5. That the countries which are the least favored by nature are those which profit most by freedom of trade. I. The equalizing of the facilities of production, is not only the shackling of certain articles of commerce, but it is the attacking of the system of mutual exchange in its very foundation principle. For this system is based precisely upon the very diversities, or, if the expression be preferred, upon the inequalities of fertility, climate, temperature, capabilities, which the protectionists seek to render null. If Guyenne sends its wines to Brittany, and Brittany sends corn to Guyenne, it is because these two provinces are, from different circumstances, induced to turn their attention to the production of different articles. Is there any other rule for international exchanges? Again, to bring against such exchanges the very inequalities of condition which excite and explain them, is to attack them in their very cause of being. The protective system, closely followed up, would bring men to live like snails, in a state of complete isolation. In short, there is not one of its Sophisms, which if carried through by vigorous deductions, would not end in destruction and annihilation. II. It is not true that the unequal facility of production, in two similar branches of industry, should necessarily cause the destruction of the one which is the least fortunate. On the turf, if one horse gains the prize, the other loses it; but when two horses work to produce any useful article, each produces in proportion to his strength; and because the stronger is the more useful, it does not follow that the weaker is good for nothing. Wheat is cultivated in every department of France, although there are great differences in the degree of fertility existing among them. If it happens that there be one which does not cultivate it, it is because, even to itself, such cultivation is not useful. Analogy will show us, that under the influence of an unshackled trade, notwithstanding similar differences, wheat would be produced in every kingdom of Europe; and if any one were induced to abandon entirely the cultivation of it, this would only be, because it would _be her interest_ to employ otherwise her lands, her capital, and her labor. And why does not the fertility of one department paralyze the agriculture of a neighboring and less favored one? Because the phenomena of political economy have a suppleness, an elasticity, and, so to speak, _a self-leveling power_, which seems to escape the attention of the school of protectionists. They accuse us of being theorists, but it is themselves who are theorists to a supreme degree, if being theoretic consists in building up systems upon the experience of a single fact, instead of profiting by the experience of a series of facts. In the above example, it is the difference in the value of lands, which compensates for the difference in their fertility. Your field produces three times as much as mine. Yes.
