But while these currencies enjoy a precarious value abroad, they have never entirely lost, not even in Russia, their purchasing power at home. A sentiment of trust in the legal money of the State is so deeply implanted in the citizens of all countries that they cannot but believe that some day this money must recover a part at least of its former value. To their minds it appears that value is inherent in money as such, and they do not apprehend that the real wealth, which this money might have stood for, has been dissipated once and for all. This sentiment is supported by the various legal regulations with which the Governments endeavor to control internal prices, and so to preserve some purchasing power for their legal tender. Thus the force of law preserves a measure of immediate purchasing power over some commodities and the force of sentiment and custom maintains, especially amongst peasants, a willingness to hoard paper which is really worthless. The presumption of a spurious value for the currency, by the force of law expressed in the regulation of prices, contains in itself, however, the seeds of final economic decay, and soon dries up the sources of ultimate supply. If a man is compelled to exchange the fruits of his labors for paper which, as experience soon teaches him, he cannot use to purchase what he requires at a price comparable to that which he has received for his own products, he will keep his produce for himself, dispose of it to his friends and neighbors as a favor, or relax his efforts in producing it. A system of compelling the exchange of commodities at what is not their real relative value not only relaxes production, but leads finally to the waste and inefficiency of barter. If, however, a government refrains from regulation and allows matters to take their course, essential commodities soon attain a level of price out of the reach of all but the rich, the worthlessness of the money becomes apparent, and the fraud upon the public can be concealed no longer. The effect on foreign trade of price-regulation and profiteer-hunting as cures for inflation is even worse. Whatever may be the case at home, the currency must soon reach its real level abroad, with the result that prices inside and outside the country lose their normal adjustment. The price of imported commodities, when converted at the current rate of exchange, is far in excess of the local price, so that many essential goods will not be imported at all by private agency, and must be provided by the government, which, in re-selling the goods below cost price, plunges thereby a little further into insolvency. The bread subsidies, now almost universal throughout Europe, are the leading example of this phenomenon.
