the raw material out of the material product of nature; that is, it is inevitably based on this monopoly use of land which is so vehemently denounced. The simplest case is that of the domestication of animals. For domestication, animals must originally be appropriated from nature, and then, instead of being consumed directly, they must be retained for increase, and for secondary products, as milk, butter, eggs, hair, wool. In time labor is spent to raise the breed and to produce artificial varieties, just as land is, by cultivation, turned into a thing utterly different from land as it appears in the "Boon of Nature." In spite of the application of labor and capital, the natural monopoly element never disappears; it recurs in new form in the case of the specialty and rareness of the highly cultivated breeds. Here, also, there is an unearned increment. If we compare the relative value of horses and other things in the Middle Ages with the value of horses and other things now, it appears that a family which had bred and sold horses from then until now, would have made far greater profits than a family who had held land and rented it from then until now.
Under the pressure of the natural monopoly of the means of subsistence, any body of men is doomed to advance to a position of general misery and want. They will be substantially equal under it, if that is any satisfaction to them. Their real and only escape lies in the arts of civilization and in science; but if they pursue those they will have to give up equality, and will have to consent that those who lead the way out shall enjoy the largest share of the gains. They have always consented to this, not because they loved the leaders, but because it was best for themselves.
