If I discover a manure which will enable me to make a piece of land produce 20 per cent more corn, I may withdraw at least a portion of my capital from the most unproductive part of my farm.
During the period of capital moving from one employment to another, the profits on that to which capital is flowing will be relatively high, but will continue so no longer than till the requisite capital is obtained.
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.
To alter the money value of commodities, by altering the value of money, and yet to raise the same money amount by taxes, is then undoubtedly to increase the burthens of society.
A rise of wages from this cause will, indeed, be invariably accompanied by a rise in the price of commodities; but in such cases, it will be found that labour and all commodities have not varied in regard to each other, and that the variation has been confined to money.
Gold and silver, like other commodities, have an intrinsic value, which is not arbitrary, but is dependent on their scarcity, the quantity of labour bestowed in procuring them, and the value of the capital employed in the mines which produce them.
I have already expressed my opinion on this subject in treating of rent, and have now only further to add, that rent is a creation of value, as I understand that word, but not a creation of wealth.
Gold and silver are no doubt subject to fluctuations, from the discovery of new and more abundant mines; but such discoveries are rare, and their effects, though powerful, are limited to periods of comparatively short duration.
If a commodity were in no way useful, – in other words, if it could in no way contribute to our gratification, – it would be destitute of exchangeable value, however scarce it might be, or whatever quantity of labour might be necessary to procure it.
Possessing utility, commodities derive their exchangeable value from two sources: from their scarcity, and from the quantity of labour required to obtain them.
If the demand for home commodities should be diminished, because of the fall of rent on the part of the landlords, it will be increased in a far greater degree by the increased opulence of the commercial classes.
Like all other contracts, wages should be left to the fair and free competition of themarket, and should never be controlled by the interference of the legislature.
After all the fertile land in the immediate neighbourhood of the first settlers were cultivated, if capital and population increased, more food would be required, and it could only be procured from land not so advantageously situated.
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.
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.
Neither machines, nor the commodities made by them, rise in real value, but all commodities made by machines fall, and fall in proportion to their durability.
