revolution. Even their quarrels, intrigues and misadventures (too often treated as merely diverting or picturesque) are part of the mechanism of our history. Under their hands the renovation of our economic life proceeded relentlessly : large-scale production replaced the scattered, decentralized mode of production ; industrial enterprises became more concentrated, more “efficient” technically, and essentially “coöperative,” where they had been purely individualistic and lamentably wasteful. But all this revolutionizing effort is branded with the motive of private gain on the part of the new captains of industry. To organize and exploit the resources of a nation upon a gigantic scale, to regiment its farmers and workers into harmonious corps of producers, and to do this only in the name of an uncontrolled appetite for private profit—here surely is the great inherent contradiction whence so much disaster, outrage and misery has flowed.

Criticism Historian Richard White argues that the builders of the transcontinental railroads have attracted a great deal of attention but the interpretations are contradictory: at first very hostile and then very favorable. At first, White says, they were depicted as: 1860s–1920s Historian John Tipple examined the writings of the 50 most influential analysts who used the robber baron model in the 1865–1914 period. He argued:The originators of the Robber Baron concept were not the injured, the poor, the faddists, the jealous, or a dispossessed elite, but rather a frustrated group of observers led at last by protracted years of harsh depression to believe that the American dream of abundant prosperity for all was a hopeless myth. ... Thus the creation of the Robber Baron stereotype seems to have been the product of an impulsive popular attempt to explain the shift in the structure of American society in terms of the obvious. Rather than make the effort to understand the intricate processes of change, most critics appeared to slip into the easy vulgarizations of the "devil-view" of history which ingenuously
