ABSTRACT
The human race, originating in a single family, has multiplied, and spread itself by degrees over the globe; and much time was of course required, before it could be adjusted to the means of subsistence, which different parts of this globe are capable of supplying. The human race would without doubt increase fourfold, perhaps tenfold in the course of a single generation. The national income can be stationary, decrease, or increase; not only must one be prepared that the population follows naturally these same changes, and will do so if the social organization is not faulty; but it is essential to the happiness of such a population that it does follow them; and if some fault in the social order prevents some classes of citizens from knowing their income.
