Have you ever considered “to whom do we owe this money”? Which bank has so much money lying around that they can afford to loan it to a nation?
If you are not familiar with fiat money take a look at “Money as Debt” or, if you have the time, “The Money Masters” on Youtube or Google and then you might begin to understand a little better the economic mess we are in and why we don’t have to/shouldn’t pay back money to banks and why we should never have bailed-out any bank.
