Final answer:
Labor strikes did not contribute to economic recovery after World War II. Instead, factors like consumer demand, the Cold War, and the Marshall Plan were key in boosting the economy.
Step-by-step explanation:
All of the following contributed to the economic recovery after World War II EXCEPT labor strikes. Consumer demand surged as wartime rationing ended, spurring economic growth. The Cold War drove military spending and technology investments, fueling economic expansion. The Marshall Plan, officially known as the European Recovery Program, pumped billions of dollars into Europe's economy, rebuilding infrastructure, restoring industrial capacity, and promoting political stability. This, in turn, created markets for American goods, further bolstering the U.S. economy. Conversely, labor strikes were not a factor that contributed to economic recovery post-war; they were a manifestation of workers' demands and potentially disruptive to economic progress.
