Cultivation, we will suppose, has just begun, and the land in use is all of the same quality, yielding a similar return to similar exertions. Wages, therefore—for, though there is neither employer nor employed, there are yet wages—will be the full produce of labor, and, making allowance for the difference of agreeableness, risk, etc., in the three pursuits, they will be on the average equal in each—that is to say, equal exertions will yield equal results. Now, if one of their number wishes to employ some of his fellows to work for him instead of for themselves, he must pay wages fixed by this full, average produce of labor.
Let a period of time elapse. Cultivation has extended, and, instead of land of the same quality, embraces lands of different qualities. Wages, now, will not be as before, the average produce of labor. They will be the average produce of labor at the margin of cultivation, or the point of lowest return. For, as men seek to satisfy their desires with the least possible exertion, the point of lowest return in culțivation must yield to labor a return equivalent to the average return in hunting and fishing.[1] Labor will no longer yield equal returns to equal exertions, but those who expend their labor on the superior land will obtain a greater produce for the same exertion than those who cultivate the inferior land. Wages, however, will still be equal, for this excess which the cultivators of the superior land receive is in reality rent, and if land has been subjected to individual ownership will give it a value. Now, if, under these changed circumstances, one member of this community wishes to hire others to work for him, he will only have to pay what the labor yields at the lowest point of cultivation. If thereafter the margin of cultivation sinks to points of lower and lower productiveness, so must wages sink; if, on the contrary, it rises, so also must wages rise; for, just as a free body tends to take the shortest route to the earth's center, so do men seek the easiest mode to the gratification of their desires.
