The reader will observe in what manner I have guarded the proposition. I am well aware, and indeed have myself stated in another place, that the price of provisions often rises, without a proportionate rise of labour: but this cannot possibly happen for any length of time, if the demand for labour continues increasing at the same rate, and the habits of the labourer are not altered, either with regard to prudence, or the quantity of work which he is disposed to perform.
The peculiar evil to be apprehended is, that the high money price of labour may diminish the demand for it; and that it has this tendency will be readily allowed, particularly as it tends to increase the prices of exportable commodities. But repeated experience has shown us that such tendencies are continually counterbalanced, and more than counterbalanced by other circumstances. And we have witnessed, in our own country, a greater and more rapid extension of foreign commerce, than perhaps was ever known, under the apparent disadvantage of a very great increase in the price of corn and labour, compared with the prices of surrounding countries.
On the other hand, instances everywhere abound of a very low money price of labour, totally failing to produce an increasing demand for it. And among the labouring classes of different countries, none certainly are so wretched as those, where the demand for labour, and the population are stationary, and yet the prices of provisions extremely low, compared with manufactures and foreign commodities. However low they may be, it is certain, that under such circumstances, no more will fall to the share of the labourer than is necessary just to maintain the actual population; and his condition will be depressed, not only by the stationary demand for labour, but by the additional evil of being able to command but a small portion of manufactures or foreign commodities, with the little surplus which he may possess. If, for instance, under a stationary population, we suppose, that in average families two thirds of the wages estimated in corn are spent in necessary provisions, it will make a great difference in the condition of the poor, whether the remaining one third will command few or many conveniencies and comforts; and almost invariably, the higher is the price of corn, the more indulgences will a given surplus purchase.
