Many people during the time of World War I believed that the entrance of the United States was due to the fact that it was good for business. It was even said by George W. Norris that people of the United States were already making money because of creation and selling of munitions for other countries. If the United States actually entered the war themselves, there would be more need for munitions, ships, and other necessities that are essential for participation in war. This would benefit workers because they would have more work to do, and therefore make more money.
It has even been documented that during World War I, 21,000 Americans became millionaires and 69,000 men had made 3 billion dollars over and above their usual income.
