Answer:
The impact of World War I on the US economy and the Great Depression is a complex and debated topic among economists and historians. While it is true that the US entry into World War I had a significant impact on the economy, it is difficult to say whether it was the sole factor that helped the US recover from the Great Depression.
The US entry into World War I did bring about significant changes to the economy. The US government spent billions of dollars on the war effort, which helped create jobs and stimulate economic growth. The demand for goods and services increased, and industries such as steel, coal, and manufacturing saw significant growth as a result.
Furthermore, the war led to a boom in US exports, as European countries were in need of US goods and materials to support their war efforts. This helped boost the US economy and provided new markets for US products.
However, it is important to note that the US economy was already showing signs of recovery before the country entered the war. The New Deal policies implemented by President Franklin D. Roosevelt, such as the creation of public works programs and new social welfare programs, helped create jobs and stimulate economic growth.
Additionally, the US economy was already benefiting from the growth of new industries, such as automobiles and radio, which helped create new jobs and stimulate economic growth.
Therefore, while the US entry into World War I had a significant impact on the economy, it is difficult to say whether or not it was the sole factor that helped the country recover from the Great Depression. The recovery was likely the result of a combination of factors, including government policies and the growth of new industries.
