The government does not NEED to pay interest on the money it prints or authorizes the printing of.

"I have never yet had anyone who could, through the use of logic and reason, justify the Federal Government borrowing the use of its own money….I believe the time will come when people will demand that this be changed.

I believe the time will come in this country when they will actually blame you and me and everyone else connected with the Congress for sitting idly by and permitting such an idiotic system to continue."
~Wright Patman, Democratic Congressman 1928-1976 Chairman, Committee on Banking and Currency 1963-1975
