To seek to confine value to exchange relations, moreover, makes it impossible to speak of the value of such things as the Capitol at Washington City, or the value of an entailed estate, or of values as existing _between_ exchanges. Nor can we make the price which a good would command at a given moment the test of its value, except in the case of the highly organized, fluid market. Land, at forced sale, notoriously often brings prices which do not correctly express its value. Moreover, even for wheat in the grain pit, the exchange test is valid only on the assumption that a comparatively small amount is to be sold. If very much is put on the market, the situation is changed, and the value falls. In other words, if "bulls" cease to be "bulls," and shift to the other side of the market, the very elements which were sustaining the value of the wheat have been weakened, and of course its value falls. "Power in exchange" is a function of two factors, (1) value and (2) saleability. A copper cent has high saleability, with little value, while land has high value with little saleability.[8] Some things have value with no saleability at all. In a socialistic community, where all lands, houses, tools, machines, etc., are owned by the state, and where such "prices" as exist are authoritatively prescribed, value and exchange would have no necessary connection. Values would remain, however, guiding the economic activity of the socialistic community, directing labor now here, now there, determining the employment of lands now in this sort of production, now in that. Exchange is only one of the manifestations of value. More fundamental, and more general, including "power in exchange," but not exhausted by it, is the power which objects of value have over the economic activities of men. This is the fundamental function of values. The entailed estate, which cannot be sold, still has power over the actions of men. The care which is taken of it, the amount of insurance which an insurance company will write on it, etc., are manifestations and measures of its value. The same may be said of the Capitol at Washington.[9]
