Base on my research this type of argument is baseless but it depends on the 100% free enterprise market system. With this system, the government doesn't have regulatory powers to protect the interest of the consumers from the financial institutions. In a situation that without the interest rate modulation, the rate charged on loans could be 40% while the rate paid on savings could be 1%. If this happens the financial institutions will not have to pay FDIC insurance to ensure the solvency of the overall system.
