Goofy question; so the perspective of history!
After defeating Napoleon at Waterloo, the British Empire solidified its hold on world power.
Economically, it was a mercantile rather than an industrial nation, which used cotton to
produce assorted fabrics, paper, vegetable oil; among many products.
Our Southern Colonies had the climate and soil to economically produce cotton;
the required ingredient being manpower, hence slavery and the rest is history.
The South became the key exporter/supplier of the raw material that kept the great
factories/mills of Birmingham, Lancashire, Manchester, and the rest, humming.
Yet that prosperity was narrow and local to the South.
The driver of American prosperity was the creativity of Carnegie in Iron and Steel, Rockefeller
in Oil and Gas and the Railroaders such as Harriman, Vanderbilt, Whitney, among many more.
These were the creators of American prosperity!
