History of North America

What was one way America profited from World War 1?

The American economy boomed during World War 1. America had been in a mild recession before the war, and industrial output increased by 20% in the first year of the war and 50% by 1918. The war created huge demand for America's raw materials, agricultural products, and manufactured goods. The war brought prosperity to the United States and made America the world's leading creditor nation.
