David Ricardo quotes - page 3
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 diminished cultivation.
David Ricardo
Mr. Malthus says, " It has been justly observed by Adam Smith that no equal quantity of productive labour employed in manufactures can ever occasion so great a reproduction as in agriculture. " If Adam Smith speaks of value, he is correct; but if he speaks of riches, which is the important point, he is mistaken; for he has himself defined riches to consist of the necessaries, conveniences, and enjoyments of human life. One set of necessaries and conveniences admits of no comparison with another set; value in use cannot be measured by any known standard; it is differently estimated by different persons.
