David Ricardo：On the Principles of Political Economy and Taxation, Excerpt 85

The natural price of all commodities excepting raw produce and labour has a tendency to fall, in the progress of wealth and population; for though, on one hand, they are enhanced in real value, from the rise in the natural price of the raw material of which they are made, this is more than counterbalanced by the improvements in machinery, by the better division and distribution of labour, and by the increasing skill, both in science and art, of the producers.
