The opinions that the price of commodities depends solely on the proportion of supply and demand, or demand to supply, has become almost an axiom in … - David Ricardo

A merchant trading with capital has been injured by the depreciation of money, as his capital has not been equal to the same extent of business as before the depreciation; but there are few merchants in this situation:—their capitals, as well as that of tradesmen, are invested in goods, ships, &c. they are rather debtors than creditors to the rest of the community... the prices of their commodities will undergo the same variations as the prices of all others, their comparative value will... be the same... The depreciation of the circulating medium has been more injurious to monied men... It may be laid down as a principle of universal application, that every man is injured or benefited by the variation of the value of the circulating medium in proportion as his property consists of money, or as the fixed demands on him in money exceed those fixed demands which he may have on others. Thus the farmer is injured by any increase in the value of money... whilst he has a fixed money rent, and fixed money taxes to pay. His produce... will sell for less, whilst his taxes and rent continue the same. ...He, more than any other class of the community, is benefited by the depreciation of money, and injured by the increase of its value.

But it is clear that the price of labour has no necessary connection with the price of food, since it depends entirely on the supply of labourers compared with the demand.

Under a system of perfectly free commerce, each country naturally devotes its capital and labour to such employments as are most beneficial to each. This pursuit of individual advantage is admirably connected with the universal good of the whole. By stimulating industry, by rewarding ingenuity, and by using most efficaciously the peculiar powers bestowed by nature, it distributes labour most effectively and most economically: while, by increasing the general mass of productions, it diffuses general benefit, and binds together, by one common tie of interest and intercourse, the universal society of nations throughout the civilized world.
