Capital may increase in quantity at the same time that its value rises. An addition may be made to the food and clothing of a country, at the same time that more labour may be required to produce the additional quantity than before; in that case not only the quantity, but the value of capital will rise.
Or capital may increase without its value increasing, and even while its value is actually diminishing; not only may an addition be made to the food and clothing of a country, but the addition may be made by the aid of machinery, without any increase, and even with an absolute diminution in the proportional quantity of labour required to produce them. The quantity of capital may increase, while neither the whole together, nor any part of it singly, will have a greater value than before.
In the first case, the natural price of wages, which always depends on the price of food, clothing, and other necessaries, will rise; in the second, it will remain stationary, or fall; but in both cases the market rate of wages will rise, for in proportion to the increase of capital will be the increase in the demand for labour; in proportion to the work to be done will be the demand for those who are to do it.
In both cases too the market price of labour will rise above its natural price; and in both cases it will have a tendency to conform to its natural price, but in the first case this agreement will be most speedily effected. The situation of the labourer will be improved, but not much improved; for the increased price of food and necessaries will absorb a large portion of his increased wages; consequently a small supply of labour, or a trifling increase in the population, will soon reduce the market price to the then increased natural price of labour.
In the second case, the condition of the labourer will be very greatly improved; he will receive increased money wages, without having to pay any increased price, and perhaps, even a diminished price for the commodities which he and his family consume; and it will not be till after a great addition has been made to the population, that the market price of wages will again sink to their then low and reduced natural price.
Thus, then, with every improvement of society, with every increase in its capital, the market wages of labour will rise; but the permanence of their rise will depend on the question, whether the natural price of wages has also risen; and this again will depend on the rise in the natural price of those necessaries, on which the wages of labour are expended.
It is not to be understood that the natural price of wages, estimated even in food and necessaries, is absolutely fixed and constant. It varies at different times in the same country, and very materially differs in different countries. It essentially depends on the habits and customs of the people. An English labourer would consider his wages under their natural rate, and too scanty to support a family, if they enabled him to purchase no other food than potatoes, and to live in no better habitation than a mud cabin; yet these moderate demands of nature are often deemed sufficient in countries where "man's life is cheap," and his wants easily satisfied. Many of the conveniences now enjoyed in an English cottage, would have been thought luxuries at an early period of our history.
From manufactured commodities always falling, and raw produce always rising, with the progress of society, such a disproportion in their relative value is at length created, that in rich countries a labourer, by the sacrifice of a very small quantity only of his food, is able to provide liberally for all his other wants.
Independently of the variations in the value of money, which necessarily affect wages, but which we have here supposed to have no operation, as we have considered money to be uniformly of the same value, wages are subject to a rise or fall from two causes:
1st. The supply and demand of labourers.
