From what has been said, we derive the principle that, with respect to given future time periods, our effective requirements for particular goods of higher order are dependent upon the availability of complementary quantities of the corresponding goods of higher order.
When cotton imports to Europe declined considerably because of the American Civil War, requirements for cotton piece goods remained evidently quite unaffected since that war could not change the needs for these goods significantly. To the extent to which there were future requirements for cotton piece goods that were not already met by finished manufactured products, there were also, as a result, requirements for the corresponding quantities of goods of higher order necessary for the production of cotton cloth. Hence these requirements also could not, on the whole, be altered significantly in any way by the civil war. But since the available quantity of one of the necessary goods of higher order, namely raw cotton, declined considerably, the natural consequence was that a part of the previous requirements for goods complementary to raw cotton with respect to the production of cotton cloth (labor services, machines, etc.) became latent, and the effective requirements for them diminished to such quantities as were necessary for processing the available quantities of raw cotton. As soon, however, as imports of raw cotton revived again, the effective requirements for these goods also experienced an increase-to the exact extent, of course, that the latent requirements diminished.
