18 INDUSTRIAL REVOLUTION AND WAGES ried on by certain social agencies, was the most significant feature of the period immediately preceding the war. The facts as to wages and working conditions which had been developed by governmental and private inquiries were so startling and so fundamental in their industrial, social, and civic significance that it was clearly apparent that they could not continue to be ignored when considered from any standpoint—whether one of humanity, public welfare, or even from the point of view of profit or the future effect- iveness and productiveness of industry.
