Rationing was absolutely necessary for the war effort. This is due to the large size of the US army. During World War I, the US had over 4 million individuals take part in military services. During World War II, it was closer to 16 million. In order for these individuals to have success, they must have the proper nutrition and meals in order to stay healthy. Failing to provide these individuals with this food could result in America becoming endangered.

Without rationing, rich individuals in American society could purchase a significant amount of the goods/resources needed for our soldiers. By restricting the consumption of the average American, the government is ensuring that American military will have the supplies needed to achieve victory.
