FED up.

Why do we have a system where the Fed lends money to the Banks so that the Banks can buy Government Bonds, which the Government then has to repay at interest?
Why doesn't the Fed lend money to the Government, charging the same interest rate that it now charges the Banks? Then the Government can pay the Fed back, and the deficit will drop by trillions.
Where does the money go? Where does the money come from? Whose money is it anyway, when you get down to it? Why is the Government lending money to the Banks so that the Government can borrow money from the Banks?
