why it can't be paid back, two reason !) some of the currency never gets printed(research fractional banking and credits) 2) the interest NEVER gets printed, so if the bank creating the interest based loans to government prints money it does not print the interest so there is not enough money in cirulation to pay the interest, do the research and you will see that the system is rigged and prepetual debt is the end result!!!!!
