Banks are important to the U.S. economy because, they help monitor the money supply. They also keep money, "safe," when the piggy bank doesn't work anymore. They can allow depositors to earn interest on their money, and allow borrowers to be granted loans. Government can affect banks in the process of buying, and selling securities. Also, the Fed can loan money to banks so the banks make additional loans to more people
Should the federal government borrow money? They have used credit. Evidence of this fact is depicted in America's debt. Credit is not free money. America does not need to continually spend money they don't have. The U.S. has already degraded itself due to it's debt, and while credit can be used as a good thing, the U.S. has already misused it, so why should they abuse money they have to pay for? I do not believe that the U.S. should use credit due to their debt, their actions (as of now), and their reputation
