Most U.S. banks are privately owned, profit-making organizations. Although they provide a service just as many other businesses, banks differ because of their importance in the macroeconomy.

2. If banks could participate in other lines of business what benefits would there be for consumers?
3. Overall, should banks be allowed to enter other lines of business?
