There were two separate forces driving the industrial revolutions in these two countries. Britain was counting on raw supplies from colonized countries, while America was finding its own raw materials as it expanded across the continent. Britain had a long history of class structure, while America was a democracy, where work and invention moved a person up the social scale. So the geographic size and the established political systems count for much of the difference. Another major difference came with the proximity of neighboring competitive countries – Germany, France, etc. The industrial output, then, was for a different market in England than in America; exports were a major concern of both, but the long journey from America to Europe made certain products uncompetitive. One other difference was transportation. Railroads in America sought to connect the two coasts, while in England the main concern was to connect London to the rural towns. In Britain, the major cities (Manchester, Glasgow, etc.) were established before the Industrial Revolution and had to adjust to accommodate the factories, population shifts, etc., while in America the cities grew up where the raw resources and geographic features were favorable (Pittsburgh, St. Louis, New Orleans, etc.), and accommodated the factories naturally.
