In short, a change of money value either way is a robbery, and none the less reprehensible because it is legal and insidious. Indeed, it is perhaps more damaging in its secondary effects because of its insidiousness. An open danger may be guarded against, but the hidden danger, known to exist, but which cannot be located or prevented, only excites fear and distrust, and checks all movement. Nor is the damage, in its secondary effects, confined to those involved in fixed money contracts. Piracy on the seas or robbery on a highway, when common, injure not alone those who are robbed. The fear and distrust engendered by such occurrences damage and delay all commerce; and the cost of protection against these menaces, or of avoiding them by taking more circuitous routes, are a burden on the whole people. So the robbery by a fluctuating money value affects, indirectly, the whole community, while the indirect effects are far worse. In the case of a decreasing money value the robbery does not bring such disastrous consequences in its train as where the change is an increase, owing to the different conditions of the people robbed. A slight decrease of money value generally brings about a stimulation of trade and industry, the rising prices of commodities acting as a spur to greater production and new enterprises. Mr. F. A. Walker, indeed, considers that for this reason, and in spite of the recognized injustice to some classes, that such a condition when slight and brought about by natural causes, is a benefit on the whole. It can hardly be admitted that robbery of one large class in a community is defensible, even if it does result in a gain to another class greater than the loss to the first. It is indisputable, however, that the opposite case, where money is increasing in value, brings such disasters in its train that it would be better, if an invariable value for money could not be attained, that the variation should be a decrease rather than an increase. In the latter case not only is the robbery equally great, but falling upon the most active, industrious, and enterprising class of the community,--for it is this class as a rule that are borrowers,--it not only imperils all they possess, but discourages, when long continued, all forms of industry and enterprise. In this way it throws thousands of men out of employment and brings suffering and hardship to thousands more. No other one cause, perhaps, is more responsible for "panics" and "hard times," with their attendant evils--tramps, pauperism, and crime. Its evils have been painted by many writers, and it is scarcely possible to exaggerate them. Of all ills, war and pestilence alone seem to fill the cup of human suffering more nearly full than the depression and stagnation of industry which is brought about by constantly declining prices.
