If we suppose for the moment, that the common and daily profits of each American amount to one dollar, it will indisputably follow that to produce an orange by _direct_ labor in America, one day's work, or its equivalent, will be requisite; whilst to produce the cost of a Portuguese orange, only one-hundredth of this day's labor is required; which means simply this, that the sun does at Lisbon what labor does at New York. Now is it not evident, that if I can produce an orange, or, what is the same thing, the means of buying it, with one-hundredth of a day's labor, I am placed exactly in the same condition as the Portuguese producer himself, excepting the expense of the transportation? It therefore follows that freedom of commerce equalizes the conditions of production direct or indirect, as much as it is possible to equalize them; for it leaves but the one inevitable difference, that of transportation. I will add that free trade equalizes also the facilities for attaining enjoyments, comforts, and general consumption; the last, an object which is, it would seem, quite forgotten, and which is nevertheless all-important; since, in fine, consumption is the main object of all our industrial efforts. Thanks to freedom of trade, we would enjoy here the results of the Portuguese sun, as well as Portugal itself; and the inhabitants of New York would have in their reach, as well as those of London, and with the same facilities, the advantages which nature has in a mineralogical point of view conferred upon Cornwall. 5. _Countries least favored by nature (countries not yet cleared of forests, for example) are those which profit most by mutual exchange._ The protectionists may suppose me in a paradoxical humor, for I go further still. I say, and I sincerely believe, that if any two countries are placed in unequal circumstances as to advantages of production, _the one of the two which is the less favored by nature, will gain more by freedom of commerce_. To prove this, I will be obliged to turn somewhat aside from the form of reasoning which belongs to this work. I will do so, however; first, because the question in discussion turns upon this point; and again, because it will give me the opportunity of exhibiting a law of political economy of the highest importance, and which, well understood, seems to me to be destined to lead back to this science all those sects which, in our days, are seeking in the land of chimeras that social harmony which they have been unable to discover in nature. I speak of the law of consumption, which the majority of political economists may well be reproached with having too much neglected. Consumption is the _end_, the final cause of all the phenomena of political economy, and, consequently, in it is found their final solution.
