The increase in the wages of labour necessarily increases the price of many commodities, by increasing that part of it which resolves itself into wages, and so far tends to diminish their consumption both at home and abroad.The same cause, however, which raises the wages of labour, the increase of stock, tends to increase its productive powers, and to make a smaller quantity of labour produce a greater quantity of work.The owner of the stock which employs a great number of labourers, necessarily endeavours, for his own advantage, to make such a proper division and distribution of employment that they may be enabled to produce the greatest quantity of work possible.For the same reason, he endeavours to supply them with the best machinery which either he or they can think of.What takes place among the labourers in a particular workhouse takes place, for the same reason, among those of a great society.The greater their number, the more they naturally divide themselves into different classes and subdivisions of employment.More heads are occupied in inventing the most proper machinery for executing the work of each, and it is, therefore, more likely to be invented.
There are many commodities, therefore, which, in consequence of these improvements, come to be produced by so much less labour than before that the increase of its price is more than compensated by the diminution of its quantity.
CHAPTER IX
Of the Profits of Stock THE rise and fall in the profits of stock depend upon the same causes with the rise and fall in the wages of labour, the increasing or declining state of the wealth of the society; but those causes affect the one and the other very differently.
The increase of stock, which raises wages, tends to lower profit.When the stocks of many rich merchants are turned into the same trade, their mutual competition naturally tends to lower its profit; and when there is a like increase of stock in all the different trades carried on in the same society, the same competition must produce the same effect in them all.
It is not easy, it has already been observed, to ascertain what are the average wages of labour even in a particular place, and at a particular time.We can, even in this case, seldom determine more than what are the most usual wages.But even this can seldom be done with regard to the profits of stock.Profit is so very fluctuating that the person who carries on a particular trade cannot always tell you himself what is the average of his annual profit.It is affected not only by every variation of price in the commodities which he deals in, but by the good or bad fortune both of his rivals and of his customers, and by a thousand other accidents to which goods when carried either by sea or by land, or even when stored in a warehouse, are liable.
It varies, therefore, not only from year to year, but from day to day, and almost from hour to hour.To ascertain what is the average profit of all the different trades carried on in a great kingdom must be much more difficult; and to judge of what it may have been formerly, or in remote periods of time, with any degree of precision, must be altogether impossible.
But though it may be impossible to determine, with any degree of precision, what are or were the average profits of stock, either in the present or in ancient times, some notion may be formed of them from the interest of money.It may be laid down as a maxim, that wherever a great deal can be made by the use of money, a great deal will commonly be given for the use of it; and that wherever little can be made by it, less will commonly be given for it.According, therefore, as the usual market rate of interest varies in any country, we may be assured that the ordinary profits of stock must vary with it, must sink as it sinks, and rise as it rises.The progress of interest, therefore, may lead us to form some notion of the progress of profit.
By the 37th of Henry VIII all interest above ten per cent was declared unlawful.More, it seems, had sometimes been taken before that.In the reign of Edward VI religious zeal prohibited all interest.This prohibition, however, like all others of the same kind, is said to have produced no effect, and probably rather increased than diminished the evil of usury.The statute of Henry VIII was revived by the 13th of Elizabeth, c.8, and ten per cent continued to be the legal rate of interest till the 21st of James I, when it was restricted to eight per cent.It was reduced to six per cent soon after the Restoration, and by the 12th of Queen Anne to five per cent.All these different statutory regulations seem to have been made with great propriety.They seem to have followed and not to have gone before the market rate of interest, or the rate at which people of good credit usually borrowed.Since the time of Queen Anne, five per cent seems to have been rather above than below the market rate.
Before the late war, the government borrowed at three per cent;and people of good credit in the capital, and in many other parts of the kingdom, at three and a half, four, and four and a half per cent.
Since the time of Henry VIII the wealth and revenue of the country have been continually advancing, and, in the course of their progress, their pace seems rather to have been gradually accelerated than retarded.They seem not only to have been going on, but to have been going on faster and faster.The wages of labour have been continually increasing during the same period, and in the greater part of the different branches of trade and manufactures the profits of stock have been diminishing.
