This population, indeed, whenever it is required, will quickly be replaced. But it is not enough that it be replaced, if it cannot find the niche, to which it is destined. Sometimes a fertile soil is in vain abundant, and remains uncultivated. There is no chance of the most numerous population assembled in its neighbourhood coming to profit by its resources. This soil has become the property of a few families; it is declared indivisible and unalienable; it will always pass to a single proprietor, according to the order of primogeniture, without the capacity either to be subjected to an emphyteutic lease, or burdened with a mortgage. The proprietor has not the capital necessary for its cultivation; he can give no security to such as have this capital, that will engage them to employ it in his land. Thus the idle population of Rome in vain calls for labour; the waste Campagna di Roma in vain calls for labourers; the social organization is bad; and so long as this shall remain unchanged, the day-labourer will perish from penury, on the surface of fields which, for want of culture, are returning to their wild state; and the population, far from increasing, will diminish.
On the same principle in manufactures, the rich proprietors of Poland will in vain require all the produce of luxury; the bad condition of the roads, prohibiting every distant transport, will in vain present superior advantages to national industry; oppression and servitude destroy all energy, all spirit of enterprise in the lower class. Elsewhere ruinous monopolies, absurd privileges, affrighting advances, ignorance, barbarity, and want of security, will render the progress of manufactures impossible; no capital will be accumulated to animate them. In those cases, to increase the population will not increase industry. The births will in vain be doubled, be quadrupled, during a certain number of years; they will not afford an additional workman, they will only be followed by a proportionably quicker mortality. The social organization is bad; so long as this shall remain unchanged, population cannot increase.
The guardian population is fed as well as recruited by the other classes. It is not sufficient that many children are born; unless their parents enjoy a certain degree of opulence, they can never bring them up to the age of men; the prince can never make soldiers of them. In this case, wars by land or sea will devour the population; whilst they employ only its superfluity, the social organization is good.
The population is always measured, in the long run, by the demand for labour. Wherever labour is required, and a sufficient wage offered, the workmen will arise to earn it. The population, with its expansive force, will occupy the place which is found vacant. Subsistence will also arise for the workmen, or in case of need, be imported. The same demand which calls a man into existence, will likeWise recompense the agricultural labour which provides him with food. If the demand for labour cease, the workman will perish, yet not without a struggle, in which not he alone will suffer, but all his brethren and his rivals. The subsistence which enabled him to live, and which henceforth he cannot pay for, and cannot demand, will, in its turn, cease to be produced. Thus national happiness rests on the demand for labour, but on a regular and perpetual demand. For, on the contrary, a demand which is intermittent, after having formed workmen, condemns them to suffering and death: it would be far better if they never had existed.
We have seen that the demand for labour, the cause of production, must be proportional to revenue which supports consumption; that this revenue, in its turn, originates in the national wealth, which wealth is formed and augmented by labour.
Thus, in political economy, all things are linked together, we move constantly in a circle; since each effect becomes a cause in its turn. Yet all things are progressive, provided that each movement is adjusted to the rest; but all stops, all retrogrades, whenever one of the movements which ought to be combined is disordered. According to the natural march of things, an augmentation of wealth will produce an augmentation of revenue; from this will arise an increase of consumption, next an increase of labour for reproduction, and therewith of population; and, finally, this new labour will, in its turn, increase the national wealth. But if, by unreasonable measures, any one of those operations is hastened without regard to all the rest, the whole system is deranged, and the poor are weighed down with suffering, instead of the happiness which was anticipated for them.
The object of society is not fulfilled, so long as the country occupied by this society, presents means of supporting a new population, of enabling it to live in happiness and abundance, whilst yet those means are not resorted to. The multiplication of happiness over the earth, is the object of Providence; it is stamped in all his works, and the duty of men in their human society is to co-operate in it.
