The rise therefore, upon the price of work, not being any augmentation of that part of the price which we call profits, as happens to be the case when a rise in demand has produced a competition among the buyers, cannot be brought down but by increasing the supply of subsistence; and were a statesman to mistake the real cause of the rise, and apply the remedy of increasing the quantity of work, in order to bring down the market, instead of augmenting the subsistence, he would occasion a great disorder; he would introduce the hurtful simple competition between people who labour for moderate profits, mentioned in the last chapter, and would throw such a discouragement upon their industry, as would quickly extinguish it altogether.

On the other hand, did he imprudently augment the subsistence, by large importations, he would put an end to the expensive improvements of the soil, and this whole enterprize would fall to nothing. Here then is a dilemma, out of which he can extricate himself by a right application of public money, only.

Such a necessary rise in the price of labour may either affect foreign exportation, or it may not, according to circumstances. If it does, the price of subsistence, at any rate, must be brought down at least to those who supply the foreign demand; if it does not affect foreign exportation, matters may be allowed to go on; but still the remedy must be ready at hand, to be applied the moment it becomes expedient.

There is one necessary augmentation upon the prices of industry, brought about by a very natural cause, viz. the increase of population, which may imply a more expensive improvement of the soil; that is, an extension of agriculture. This augmentation may very probably put a stop to the augmentation of demand for many branches of manufactures, consequently may stop the progress of industry; and if the same causes continue to operate in a greater degree, it may also cut off a part of the former demand, may discredit the market, open a door to foreign consumption, and produce the inconveniencies of poverty and distress, in proportion to the degree of negligence in the statesman.

I shall now give another example, of a very natural augmentation upon the intrinsic value of work, which does not proceed from the increase of population, but from the progress of industry itself; which implies no internal vice in a state, but which is the necessary consequence of the reformation of a very great one. This augmentation must be felt less or more in every country, in proportion as industry becomes extended.

We have said, that the introduction of manufactures naturally tends to purge the lands of superfluous mouths: now this is a very slow and gradual operation. A consequence of it was said to be (Book I. Chap. xx.) an augmentation of the price of labour, because those who have been purged off, must begin to gain their whole subsistence at the expence of those who employ them.

If therefore, in the infancy of industry, any branch of it shall find itself assisted in a particular province, by the cheap labour of those mouths superfluously fed by the land, examples of which are very frequent, this advantage must diminish, in proportion as the cause of it ceases; that is, in proportion as industry is extended, and as the superfluous mouths are of consequence purged off.

This circumstance is of the last importance to be attended to by a statesman. Perhaps it was entirely owing to it, that industry was enabled to set up its head in this corner. How many examples could I give, of this assistance given to manufactures in different provinces, where I have found the value of a day’s work, of spinning, for example, not equal to half the nourishment of the person. This is a great encouragement to the making of cloths; and accordingly we see some infant manufactures dispute the market with the produce of the greatest dexterity; the distaff dispute prices with the wheel. But when these provinces come to be purged of their superfluous mouths, spinning becomes a trade, and the spinners must live by it. Must not then prices naturally rise? And if these are not supported by the statesman, or if assistance is not given to these poor manufacturers, to enable them to increase their dexterity, in order to compensate what they are losing in cheapness, will not their industry fail? Will not the poor spinners be extinguished? For it is not to be expected, that the landlord will receive them back again from a principle of charity, after he has discovered their former uselesness[uselesness].

A third cause of a necessary augmentation upon the intrinsic value of goods proceeds from taxes. A statesman must be very negligent indeed, if he does not attend to the immediate consequences of his own proper operations. I shall not enlarge on this at present, as it would be an unnecessary anticipation; but I shall return, to resume the part of my reasoning which I broke off abruptly.

I have observed, how the same cause which stops the progress of industry, gives an encouragement to agriculture: how the rise in the price of subsistence necessarily increases the price of work to an industrious and well-employed people: how this cuts off a part of the demand for work, or sends it to a foreign market.
