Thus, in essence, the public had obtained the reform which it had been demanding for years. The reorganized commission did not hesitate to exercise its new powers. It soon began actually fixing rates, and from being a half-alive despised institution it rapidly developed into one of the most powerful agencies of administration. In the succeeding ten years its powers were still further enlarged by acts of Congress and the privilege of fixing charges practically passed out of the hands of the railroads into the control of the Interstate Commerce Commission. The railroads, that is, practically lost the power to regulate their own income. Meanwhile, the progressive movement in American politics had led to the creation of commissions in most of the States, with similar authority over rate making within the States, besides exercising numerous other powers over service and capitalization. Many railroads fell upon evil days and receiverships again became common. Naturally the railroad managers attributed these calamities to the fact that they were so constantly being regulated; but they probably pushed this claim too far, for the causes of their troubles were more complex. In 1916, in the heat of a political campaign, the Federal Government took a step which introduced a new principle into railroad management and made the roads practically helpless. The four brotherhoods of railroad operatives were making demands for a so-called eight-hour day, and threatened a general strike that would paralyze all business and industry and throw the whole life of the nation into chaos. Properly to appreciate the consequences of this event, it is necessary to keep in mind the fact that the plea for an "eight-hour day" was spurious. An eight-hour day cannot be rigidly enforced on railroads; the workmen well knew this, and indeed they did not really demand such working hours. What they asked for was a full day's pay for eight hours and "time and a half" pay for all in excess of that amount; that is, they demanded an increase in wages. President Wilson, having failed in his attempt to settle the difficulty by arbitration, compelled a Democratic Congress over which his sway was absolute to pass a law-sponsored by Chairman Adamson of the House Committee on Interstate Commerce--which granted practically what the unions demanded. In passing this law, Congress asserted an entirely new power which no one had ever suspected that it possessed--that of fixing the wages which should be paid by common carriers and possibly by other corporations engaged in interstate commerce. The railroads immediately took the case to the United States Supreme Court, which promptly sustained the law. This decision, unquestionably the most radical in the history of that body, declared virtually that Congress could pass any law regulating railroads which the public interest demanded.
