The Postwar Economy: 1945-1960. As the Cold Warunfolded in the decade and a half after World War II, the United States experienced phenomenal economic growth. The war brought the return of prosperity, and in the postwar period the United States consolidated its position as the world's richest country.

were in trouble as well as provided emergency help. They also proposed
and passed many laws that would help prevent this kind of situation in
the future.
