Note 29 — Chapter I · : THE PHYSIOCRATS

“A weaver buys food and clothing, giving 150 francs for them, together with a quantity of flax, for which he gives 50 francs. The cloth will be sold for 200 francs, a sum that will cover all expenditure.” (Mercier de la Rivière, vol. ii, p. 598.) “Industry merely superimposes value, but does not create any which did not previously exist.” (Ibid.)
