A few of these abuses are fairly obvious without a full inquiry, and may be illustrated here because their existence in time of peace may throw light on the operations of trade in belligerent states, and indirectly, by suggesting a few of the results of war, may lead us to some of its motives and occasions. Such abuses may be most easily identified in opposition to the national rights which they infringe. FOOTNOTES: [Footnote 21: So in Germany the fixing of maximum prices for pigs and potatoes was immediately followed by an almost complete withdrawal from the market of potatoes and pigs--the German farmers refused to sell except at their own inflated prices. Cf. quotations from the German Press in _The New Statesman_ of January 29, 1916.] [Footnote 22: "Ces choses sont plutot des moyens que l'on emploie pour travailler a faire prosperer l'Etat qu'ils ne sont l'essence de sa prosperite."--Rousseau, _Political Writings_, I, 345 (C. E. Vaughan's edition).] Sec. 7 Duties of Commerce to the State The State has a primary right to be fairly served. Prices should not be arbitrarily raised by any wholesale merchant who happens to be in a position to do so, or by any cartel of dealers in league for that purpose. Prices should be regulated by the cost of production, and should not be an indication of demand; they should rise beyond the cost of production augmented by a fair profit only when the supply is insufficient (production not being artificially restrained) to meet some abnormal demand, and only as a means of checking and regulating the excessive demand. We find instead that any dealer or group of dealers will raise their prices almost absent-mindedly as soon as they are in a position to meet a demand which cannot be postponed. Thus it is that governments are habitually overcharged in all their contracts and purchases; because governments have neither the time nor the opportunity for casual dealings, and because they do not undertake such transactions at all unless their absolute necessity has already been decided.[23] So at the beginning of the war English warehouses were full of all sorts of commodities required by the governments of the Allies; but the urgency of war prevented any sort of bargaining; and the private merchants took advantage of the situation to the amount of about two hundred per cent. At present however I am dealing with trade in time of peace and I must not flavour the ordinary facts with any consideration of War Office contracts. It is enough to state the fact that in ordinary times the private tradesman regards a special demand as an opportunity for raising prices rather than as the stimulus of supply; a rule which is most easily detected in the experience of Government departments.
