How did World War 1 affect Americans socially, politically, and economically?

Economic Impact on the United States. World War 1 took the United States out of a recession into a 44 month economic boom. U.S. exports to Europe increased as these countries geared up for War. Later, U.S spending increased as it prepared to enter to War itself.

la segunda guerra mundial comenzó el 1 de septiembre de 1939 y terminó el 2 de septiembre de 1945. ¡espero que esto ayude!
