Answer:
Because the federal government needs to regulate the production of war goods, as well as having to control the country's spending to prevent possible shortages.
Step-by-step explanation:
During a war, the federal government must administer the country's economy with the greatest possible responsibility, because during a war, the production of a country is compromised. Much of the public money is spent on the troops, so it is important for the federal government to manage the country's economy by regulating the production of war goods, such as the production of goods for the population, avoiding a possible shortage of products.
