The manufacturing industry is a really important sector in the United States as it helped build the middle class after the second World War. In the early 21st century accounted for 10% of corporate profits. Unfortunately the employment in this sector is estimated to decline in the coming years.
The United States government used propaganda as a way to make Americans support the War. The Federal government used posters, films, and propaganda to start the spirit of patriotism and increase the number of labor and military force.

The Government propaganda was successful, American citizens were very supportive of the War and even helped the government by donating metals to build more military gear.
