§ 7. —by the emigration of Capital.

This brings us to the last of the counter-forces which check the downward tendency of profits in a country whose capital increases faster than that of its neighbors, and whose profits are therefore nearer to the minimum. This is, the perpetual overflow of capital into colonies or foreign countries, to seek higher profits than can be obtained at home. I believe this to have been for many years one of the principal causes by which the decline of profits in England has been arrested. It has a twofold operation: In the first place, it does what a fire, or an inundation, or a commercial crisis would have done—it carries off a part of the increase of capital from which the reduction of profits proceeds; secondly, the capital so carried off is not lost, but is chiefly employed either in founding colonies, which become large exporters of cheap agricultural produce, or in extending and perhaps improving the agriculture of older communities.

In countries which are further advanced in industry and population, and have therefore a lower rate of profit, than others, there is always, long before the actual minimum is reached, a practical minimum, viz., when profits have fallen so much below what they are elsewhere that, were they to fall lower, all further accumulations would go abroad. As long as there are old countries where capital increases very rapidly, and new countries where profit is still high, profits in the old countries will not sink to the rate which would put a stop to accumulation: the fall is stopped at the point which sends capital abroad.
