In rich and powerful countries where large capitals are invested in machinery, more distress will be experienced from a revulsion in trade, than in poorer countries where there is proportionally a much smaller amount of fixed, and a much larger amount of circulating capital, and where consequently more work is done by the labour of men. It is not so difficult to withdraw a circulating as a fixed capital, from any employment in which it may be engaged. It is often impossible to divert the machinery which may have been erected for one manufacture, to the purposes of another; but the clothing, the food, and the lodging of the labourer in one employment may be devoted to the support of the labourer in another, or the same labourer may receive the same food, clothing, and lodging, whilst his employment is changed. This, however, is an evil to which a rich nation must submit; and it would not be more reasonable to complain of it, than it would be in a rich merchant to lament that his ship was exposed to the dangers of the sea, whilst his poor neighbour's cottage was safe from all such hazard.
From contingencies of this kind, though in an inferior degree, even agriculture is not exempted. War, which in a commercial country, interrupts the commerce of states, frequently prevents the exportation of corn from countries where it can be produced with little cost, to others not so favourably situated. Under such circumstances an unusual quantity of capital is drawn to agriculture, and the country which before imported becomes independent of foreign aid. At the termination of the war, the obstacles to importation are removed, and a competition destructive to the home-grower commences, from which he is unable to withdraw, without the sacrifice of a great part of his capital. The best policy of the state would be, to lay a tax, decreasing in amount from time to time, on the importation of foreign corn, for a limited number of years, in order to afford to the home-grower an opportunity to withdraw his capital gradually from the land. In so doing the country might not be making the most advantageous distribution of its capital, but the temporary tax to which it was subjected, would be for the advantage of a particular class, the distribution of whose capital was highly useful in procuring a supply of food when importation was stopped. If such exertions in a period of emergency were followed by risk of ruin on the termination of the difficulty, capital would shun such an employment. Besides the usual profits of stock, farmers would expect to be compensated for the risk which they incurred of a sudden influx of corn, and therefore the price to the consumer, at the seasons when he most required a supply, would be enhanced, not only by the superior cost of growing corn at home, but also by the insurance which he would have to pay, in the price, for the peculiar risk to which this employment of capital was exposed. Notwithstanding then, that it would be more productive of wealth to the country, at whatever sacrifice of capital it might be done, to allow the importation of cheap corn, it would perhaps be advisable to charge it with a duty for a few years.
In examining the question of rent, we found, that with every increase in the supply of corn, and with the consequent fall of its price, capital would be withdrawn from the poorer land; and land of a better description, which would then pay no rent, would become the standard by which the natural price of corn would be regulated. At 4l. per quarter, land of an inferior quality, which may be designated by No. 6, might be cultivated; at 3l. 10s. No. 5; at 3l. No. 4, and so on. If corn, in consequence of permanent abundance, fell to 3l. 10s. the capital employed on No. 6 would cease to be employed; for it was only when corn was at 4l. that it could obtain the general profits, even without paying rent: it would therefore be withdrawn to manufacture those commodities with which all the corn grown on No. 6 would be purchased and imported. In this employment it would necessarily be more productive to its owner, or it would not be withdrawn from the other; for if he could obtain more corn by growing it on land for which he paid no rent, than by manufacturing a commodity with which he purchased it, its price could not be under 4l.
It has, however, been said that capital cannot be withdrawn from the land; that it takes the form of expenses, which cannot be recovered, such as manuring, fencing, draining, &c., which are necessarily inseparable from the land. This is in some degree true; but that capital which consists of cattle, sheep, hay and corn ricks, carts, &c. may be withdrawn; and it always becomes a matter of calculation whether these shall continue to be employed on the land, notwithstanding the low price of corn, or whether they shall be sold, and their value transferred to another employment.
Suppose, however, the fact to be as stated, and that no part of the capital could be withdrawn; the farmer would continue to raise corn, and precisely the same quantity too, at whatever price it might sell; for it could not be his interest to produce less, and if he did not so employ his capital, he would obtain from it no return whatever. Corn could not be imported, because he would sell it lower than 3l. 10s. rather than not sell it at all, and by the supposition the importer could not sell it under that price. Although then the farmers, who cultivated land of this quality, would undoubtedly be injured by the fall in the exchangeable value of the commodity which they produced,—how would the country be affected? We should have precisely the same quantity of every commodity produced, but raw produce and corn would sell at a much cheaper price. The capital of a country consists of its commodities, and as these would be the same as before, reproduction would go on at the same rate. This low price of corn would however only afford the usual profits of stock to the land, No. 5, which would then pay no rent, and the rent of all better land would fall: wages would also fall, and profits would rise.
However low the price of corn might fall; if capital could not be removed from the land, and the demand did not increase, no importation would take place; for the same quantity as before would be produced at home. Although there would be a different division of the produce, and some classes would be benefited, and others injured, the aggregate of production would be precisely the same, and the nation collectively would neither be richer nor poorer.
But there is this advantage always resulting from a relatively low price of corn,—that the division of the actual production is more likely to increase the fund for the maintenance of labour, inasmuch as more will be allotted, under the name of profit, to the productive class, a less, under the name of rent, to the unproductive class.
This is true, even if the capital cannot be withdrawn from the land, and must be employed there, or not be employed at all: but if great part of the capital could be withdrawn, as it evidently could, it will be only withdrawn, when it will yield more to the owner by being withdrawn than by being suffered to remain where it was; it will only be withdrawn then, when it can elsewhere be employed more productively both for the owner and the public. He consents to sink that part of his capital which cannot be separated from the land, because with that part which he can take away, he can obtain a greater value, and a greater quantity of raw produce, than by not sinking this part of the capital. His case is precisely similar to that of a man who has erected machinery in his manufactory at a great expense, machinery which is afterwards so much improved upon by more modern inventions, that the commodities manufactured by him very much sink in value. It would be entirely a matter of calculation with him whether he should abandon the old machinery, and erect the more perfect, losing all the value of the old, or continue to avail himself of its comparatively feeble powers. Who, under such circumstances, would exhort him to forego the use of the better machinery, because it would deteriorate or annihilate the value of the old? Yet this is the argument of those who would wish us to prohibit the importation of corn, because it will deteriorate or annihilate that part of the capital of the farmer which is for ever sunk in land. They do not see that the end of all commerce is to increase production, and that by increasing production, though you may occasion partial loss, you increase the general happiness. To be consistent, they should endeavour to arrest all improvements in agriculture and manufactures, and all inventions of machinery; for though these contribute to general abundance, and therefore to the general happiness, they never fail, at the moment of their introduction, to deteriorate or annihilate a part of the existing capital of farmers and manufacturers.
Agriculture like all other trades, and particularly in a commercial country, is subject to a re-action, which, in an opposite direction, succeeds the action of a strong stimulus. Thus, when war interrupts the importation of corn, its consequent high price attracts capital to the land, from the large profits which such an employment of it affords; this will probably cause more capital to be employed, and more raw produce to be brought to market than the demands of the country require. In such case, the price of corn will fall from the effects of a glut, and much agricultural distress will be produced, till the average supply is brought to a level with the average demand.
