"Now, early in 1865, the war is over. The North does not especially want free Negroes, it wants trade and wealth. The South does not want a particular interpretation of the Constitution. It wants cheap Negro labor and the political and social power based on it. Had there been no Negroes, there would have been no war. Had no Negroes survived the war, peace would have been difficult because of hatred, loss and bitter fried. But its logical path would have been straight.The South would have returned to its place in congress with less than its former representation because of the growing North and West. These areas of growing manufacture and agriculture, railroad building and corporations, would have held the political power over the South until the South united with the new insurgency of the West or the Eastern democratic ideals. Industrialization might even have brought a third party representing labor and raised the proletariat to dominance."
