[...] two quite distinct but persistently undifferentiated visions of the future dominated the triumphant North after the war. One was the prolongation of Puritan idealism, transformed by the frontier into a theory of universal democracy, and now expressed by Abolitionists like Wendell Phillips, students of civilization like Charles Sumner, and leaders of the common people like Thaddeus Stephens, together with some of the leaders of the new labor movement. The other trend was entirely different and is confused with the democratic ideal because the two ideals lay confused in so many individual minds. This was the development of industry in America and of a new industrial philosophy.

The new industry had a vision not of work but of wealth; not of planned accomplishment, but of power. It became the most conscienceless, unmoral system of industry which the world has experienced. It went with ruthless indifference towards waste, death, ugliness and disaster, and yet reared the most stupendous machine for the efficient organization of work which the world has ever seen.

Thus the end of the Civil War was the beginning of vast economic development in the industrial expansion of the East, in the agricultural growth of the Middle West, in the new cattle industry of the plains, in the mining enterprises of the Rockies, in the development of the Pacific Coast, and in the reconstruction of the Southern market.
