As the revenue of the farmer is realized in raw produce, or in the value of raw produce, he is interested, as well as the landlord, in its high exchangeable value, but a low price of produce may be compensated to him by a great additional quantity.

Profits might also increase, because improvements might take place in agriculture, or in the implements of husbandry, which would augment the produce with the same cost of production.

It is here we come to the heart of the matter. The economic principle of comparative advantage', 'a country may, in return for manufactured commodities, import corn even if it can be grown with less labour than in the country from which it is imported

Utility then is not the measure of exchangeable value, although it is absolutely essential to it.

The produce of the earth - all that is derived from its surface by the united application of labour, machinery, and capital, is divided among three classes of the community, namely, the proprietor of the land, the owner of the stock or capital necessary for its cultivation, and the labourers by whose industry it is cultivated.

Labour, like all other things which are purchased and sold... has its natural and its market price.

If then the prosperity of the commercial classes, will most certainly lead to accumulation of capital, and the encouragement of productive industry; these can by no means be so surely obtained as by a fall in the price of corn.
