As most of you know, the FED owns a lot of our national debt. On the Bonds that they have bought, the FED directly deposits the interest received into the Treasury. The end result is that the bonds have no real interest rate attached to them. So now, I ask the question that I have posed before. Why can't we have the FED buy all of our debt for no interest? If so is there a limit to how much we can borrow? If there is no limit than why are people worried about our national debt? There is noting to worry about. Right?
