In Europe, the expenses attending the carriage of corn are often considerable. They form a natural barrier to importation;and even the country which habitually depends upon foreign corn, must have the price of its raw produce considerably higher than the general level. Practically, also, the prices of raw produce, in the different countries of Europe, will be variously modified by very different soils, very different degrees of taxation, and very different degrees of improvement in the science of agriculture. Heavy taxation, and a poor soil, may occasion a high comparative price of raw produce, or a considerable dependence on other countries, without great wealth and population; while great improvements in agriculture and a good soil may keep the price of produce low, and the country independent of foreign corn, in spite of considerable wealth. But the principles laid down are the general principles on the subject; and in applying them to any particular case, the particular circumstances of such case must always be taken into consideration.
With regard to improvements in agriculture, which in similar soils is the great cause which retards the advance of price compared with the advance of produce; although they are sometimes very powerful, they are rarely found sufficient to balance the necessity of applying to poorer land, or inferior machines. In this respect, raw produce is essentially different from manufactures.
The real price of manufactures, the quantity of labour and capital necessary to produce a given quantity of them, is almost constantly diminishing; while the quantity of labour and capital, necessary to procure the last addition that has been made to the raw produce of a rich and advancing country, is almost constantly increasing. We see in consequence, that in spite of continued improvements in agriculture, the money price of corn is ceteris paribus the highest in the richest countries, while in spite of this high price of corn, and consequent high price of labour, the money price of manufactures still continues lower than in poorer countries.
I cannot then agree with Adam Smith, in thinking that the low value of gold and silver is no proof of the wealth and flourishing state of the country, where it takes place. Nothing of course can be inferred from it, taken absolutely, except the abundance of the mines; but taken relatively, or in comparison with the state of other countries, much may be inferred from it.
If we are to measure the value of the precious metals in different countries, and at different periods in the same country, by the price of corn and labour, which appears to me to be the nearest practical approximation that can be adopted (and in fact corn is the measure used by Adam Smith himself), it appears to me to follow, that in countries which have a frequent commercial intercourse with each other, which are nearly at the same distance from the mines, and are not essentially different in soil; there is no more certain sign, or more necessary consequence of superiority of wealth, than the low value of the precious metals, or the high price of raw produce.(15*)It is of importance to ascertain this point; that we may not complain of one of the most certain proofs of the prosperous condition of a country.
It is not of course meant to be asserted, that the high price of raw produce is, separately taken, advantageous to the consumer; but that it is the necessary concomitant of superior and increasing wealth, and that one of them cannot be had without the other.(16*)With regard to the labouring classes of society, whose interests as consumers may be supposed to be most nearly concerned, it is a very short-sighted view of the subject, which contemplates, with alarm, the high price of corn as certainly injurious to them. The essentials to their well being are their own prudential habits, and the increasing demand for labour. And I do not scruple distinctly to affirm, that under similar habits, and a similar demand for labour, the high price of corn, when it has had time to produce its natural effects, so far from being a disadvantage to them, is a positive and unquestionable advantage.
To supply the same demand for labour, the necessary price of production must be paid, and they must be able to command the same quantities of the necessaries of life, whether they are high or low in price.(17*) But if they are able to command the same quantity of necessaries, and receive a money price for their labour, proportioned to their advanced price, there is no doubt that, with regard to all the objects of convenience and comfort, which do not rise in proportion to corn (and there are many such consumed by the poor), their condition will be most decidedly improved.
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.
