Productive Co-Operation Of The Three Factors. The Three Great Periods Of A Nation’s Economy. The relation of the three factors to one another is necessarily very different in different branches of production. For instance, in the case of cattle-raising on a prairie, labor does very little, land almost everything. Hence an extensive, thinly populated country is best adapted to this species of production. But where land is scarce, as in wealthy and populous cities, human activity should be directed into those branches of industry which need capital and labor, as manufactures and the trades. (§ 198.)(305) Looked at from this point of view, the history of the development of the public economy of every people may be divided into three great periods. In the earliest period, nature is the element that predominates everywhere. The woods, waters and meadows afford food almost spontaneously to a scanty population. This is the Saturnian or golden age of which the sagas tell. Wealth, properly speaking, does not exist here, and those who do not possess a piece of land run the risk of becoming completely dependent on, or even the slave of a land owner. In the second period, that through which all modern nations have passed since the later part of the middle ages, the element, labor, acquires an ever increasing importance. Labor favors the origin and development of cities as well as exclusive rights, the rights of boroughs and guilds by means of which labor is, so to speak, capitalized. A middle class is formed intermediate between the serfs and the owners of the soil. In the third period, capital, if we may so speak, gives tone to everything. The value of land is vastly increased by the expenditure of capital on it, and in manufactures, machine labor preponderates over the labor of the human hand.(306) The national wealth undergoes a daily increase; and it is the “capitalism” which first gives an independent existence to the economic activity of man; just in the same way that law is, as it were, emancipated from land-ownership, from the church and the family only in the constitutional state (_Rechtsstaat_).(307) But, during this period, the middle class with its moderate ease and solid culture may decrease in numbers, and colossal wealth be confronted with the most abject misery.(308) Although these three periods may be shown to exist in the history of all highly civilized countries, the nations of antiquity, relatively speaking, never advanced far beyond the second, even in their palmiest days. A great part of that which is accomplished among us by means of capital and of machines, the Greeks and Romans performed by the labor of slaves. Leaving Christianity out of the question, nearly all the minor differences between the public economy of the ancients and that of the moderns may be reduced to this fundamental distinction.(309)(310) Section XLVIII.
