The income of every class of society is to some extent affected by these more or less periodic fluctuations. They are in part the price paid for progress under the constantly shifting conditions of our dynamic industry. In part they are the proof of industrial maladjustment. The force of the shocks will no doubt be much reduced by better banking and business methods, and by a sound currency system. More important still, the development of moderation, conservatism, and a less speculative spirit among the leaders of business will do much toward softening the asperity of these scourges of industry.
