Whence comes this incongruity? It lies in the nature of industrial competition and the commercial crises which arise from them. In the present unregulated production and distribution of the means of subsistence, which is carried on not directly for the sake of supplying needs, but for profit, in the system under which every one works for himself to enrich himself, disturbances inevitably arise at every moment. For example, England supplies a number of countries with most diverse goods. Now, although the manufacturer may know how much of each article is consumed in each country annually, he cannot know how much is on hand at every given moment, much less can he know how much his competitors export thither. He can only draw most uncertain inferences from the perpetual fluctuations in prices, as to the quantities on hand and the needs of the moment. He must trust to luck in exporting his goods. Everything is done blindly, as guess-work, more or less at the mercy of accident. Upon the slightest favourable report, each one exports what he can, and before long such a market is glutted, sales stop, capital remains inactive, prices fall, and English manufacture has no further employment for its hands. In the beginning of the development of manufacture, these checks were limited to single branches and single markets; but the centralising tendency of competition which drives the hands thrown out of one branch into such other branches as are most easily accessible, and transfers the goods which cannot be disposed of
