Population, when unchecked, goes on doubling itself every 25 years or increases in a geometrical ratio.

The doctrine of population has been conspicuously absent, not because I doubt in the least its truth and vast importance, but because it forms no part of the direct problem of economics.

In general it may be said that demand is quite as necessary to the increase of capital as the increase of capital is to demand.

Population regulates itself by the funds which are to employ it, and therefore always increases or diminishes with the increase or the diminution of capital. Every reduction of capital is therefore necessarily followed by a less effective demand for corn, by a fall in price, and by a diminished cultivation.

Thirty or forty proprietors, with incomes answering to between one thousand and five thousand a year, would create a much more effectual demand for the necessaries, conveniences, and luxuries of life, than a single proprietor possessing a hundred thousand a year.

The friend of the present order of things condemns all political speculations in the gross.

If a country can only be rich by running a successful race for low wages, I should be disposed to say at once, perish such riches!
