What happened to England after the American Revolution

Americans like to think that Britain suffered a severe loss when the colonies became independent. That's true if you look at the lost potential and the later industrialization and natural resources that Britain lost title to, but in the late 18th century, the American colonies were viewed by Britain as "the farm" and little else. America was an agricultural economy, with no known gold, silver, spice or tea trade to interest Britain. The one thing America had that Britain wanted was cotton--good quality and cheap.

In summary, Britain did quite well without the American colonies.
After the loss of the colonies, despite the fact that King George went insane (not because Britain lost the colonies) Britain was doing quite well and by the mid-19th century was leading the industrial revolution with massive coal reserves and engineering skills. Railroads had their infancy in Britain, the empire was growing and prospering and Britain ruled the seas.

By the later part of the 19th century, Queen Victoria was at the helm and Britain was in her golden period with prosperity and fortunes for fortunate industrialists and traders.
