§ 3. In old and opulent countries, profits habitually near to the minimum.

We now arrive at the fundamental proposition which this chapter is intended to inculcate. When a country has long possessed a large production, and a large net income to make savings from, and when, therefore, the means have long existed of making a great annual addition to capital (the country not having, like America, a large reserve of fertile land still unused), it is one of the characteristics of such a country that the rate of profit is habitually within, as it were, a hand's breadth of the minimum, and the country, therefore, on the very verge of the stationary state. My meaning is, that it would require but a short time to reduce profits to the minimum, if capital continued to increase at its present rate, and no circumstances having a tendency to raise the rate of profit occurred in the mean time.

In England, the ordinary rate of interest on government securities, in which the risk is next to nothing, may be estimated at a little more than three per cent: in all other investments, therefore, the interest or profit calculated upon (exclusively of what is properly a remuneration for talent [pg 502] or exertion) must be as much more than this amount as is equivalent to the degree of risk to which the capital is thought to be exposed. Let us suppose that in England even so small a net profit as one per cent, exclusive of insurance against risk, would constitute a sufficient inducement to save, but that less than this would not be a sufficient inducement. I now say that the mere continuance of the present annual increase of capital, if no circumstance occurred to counteract its effect, would suffice in a small number of years to reduce the rate of net profit to one per cent.

To fulfill the conditions of the hypothesis, we must suppose an entire cessation of the exportation of capital for foreign investment. We must suppose the entire savings of the community to be annually invested in really productive employment within the country itself, and no new channels opened by industrial inventions, or by a more extensive substitution of the best-known processes for inferior ones.

The difficulty in finding remunerative employment every year for so much new capital would not consist in any want of a market. If the new capital were duly shared among many varieties of employment, it would raise up a demand for its own produce, and there would be no cause why any part of that produce should remain longer on hand than formerly. What would really be, not merely difficult, but impossible, would be to employ this capital without submitting to a rapid reduction of the rate of profit.

As capital increased, population either would also increase, or it would not. If it did not, wages would rise, and a greater capital would be distributed in wages among the same number of laborers. There being no more labor than before, and no improvements to render the labor more efficient, there would not be any increase of the produce; and, as the capital, however largely increased, would only obtain the same gross return, the whole savings of each year would be exactly so much subtracted from the profits of the next and of every following year.

[pg 503]

This can be illustrated by supposing that the whole capital is handed out to the producers in a vessel which is returned full at the end of the period of production with the original outlay, plus an advance called profit. B C represents the total outlay, A C the total produce, and A B the profit on B C. Now, since the conditions of production remain the same, the same number of laborers can produce, as before, no more than A C; even though in the second year some of last year's profit, represented by D B, is saved and added to the outlay by the capitalist. If D C is now the outlay of capital, the profit can only be A C, minus D C, or A D; that is, the profit of the second year is diminished by D B, exactly the amount of savings of the year before. And this would be repeated each successive year, each saving added to B C being “exactly so much subtracted from the profits of the next and of every following year.”

It is hardly necessary to say that in such circumstances profits would very soon fall to the point at which further increase of capital would cease. An augmentation of capital, much more rapid than that of population, must soon reach its extreme limit, unless accompanied by increased efficiency of labor (through inventions and discoveries, or improved mental and physical education), or unless some of the idle people, or of the unproductive laborers, became productive.

If population did increase with the increase of capital and in proportion to it, the fall of profits would still be inevitable. Increased population implies increased demand for agricultural produce. In the absence of industrial improvements, this demand can only be supplied at an increased cost of production, either by cultivating worse land, or by a more elaborate and costly cultivation of the land already under tillage. The cost of the laborer's subsistence is therefore increased, and, unless the laborer submits to a deterioration of his condition, profits must fall. In an old country like England, if, in addition to supposing all improvement in domestic agriculture suspended, we suppose that there is no increased production in foreign countries for the English market, the fall of profits would be very rapid. If both these avenues to an increased supply of food were [pg 504] closed, and population continued to increase, as it is said to do, at the rate of a thousand a day, all waste land which admits of cultivation in the existing state of knowledge would soon be cultivated, and the cost of production and price of food would be so increased that, if the laborers received the increased money wages necessary to compensate for their increased expenses, profits would very soon reach the minimum. The fall of profits would be retarded if money wages did not rise, or rose in a less degree; but the margin which can be gained by a deterioration of the laborers' condition is a very narrow one: in general, they can not bear much reduction; when they can, they have also a higher standard of necessary requirements, and will not. On the whole, therefore, we may assume that in such a country as England, if the present annual amount of savings were to continue, without any of the counteracting circumstances which now keep in check the natural influence of those savings in reducing profit, the rate of profit would speedily attain the minimum, and all further accumulation of capital would for the present cease.

Mr. Carey, on the other hand, asserts the existence of a law of increasing returns from land, and that, while wages are constantly increasing with the progress of society, there is a diminution in the rate of profit, although the increasing returns permit an increase of absolute, if not of proportional, profit. That is, although wages increase more in proportion than profit, there is still a larger gross amount to be divided among capitalists as profit, out of a larger product.
