The present industrial era brought with it a new governing class, as every considerable change in human environment must bring with it a governing class to give it expression. Perhaps, for lack of a recognized name, I may describe this class as the industrial capitalistic class, composed in the main of administrators and bankers. I conjecture that this class attained its acme of popularity and power, at least in America, toward the close of the third quarter of the nineteenth century. Almost at the opening of the present century a progressively rigorous opposition found for its mouthpiece the President of the Union himself. If Mr. Roosevelt became, what his adversaries are pleased to call, an agitator, his agitation had a cause which is as deserving of study as is the path of a cyclone.
