Industrialism dividing the
Northeast from the agricultural South contributed inevitably to the approach of war.

By 1850 the economy of New England and the Northeastern states had changed
forever. Industrialization and the factory system replaced shipping and mercantile trade as the
basis of wealth and power.
Henry Clay's "American System" included a factory production new to the world:
--displacement of hand labor by machine labor,
--increased production of finished objects by exact duplication of interchangeable parts,
--increased precision with development of automated machine tools.
The factories of the 1840's and 1850's had become essentially the factories of today in rationale
of progress. The exercise of the New England Yankee's passion for economy, neatness, and
logical order had made the world over.

Year of Decision 1846 (Boston: Little Brown and Company, 1943), 214-15.
