According to the Irish comic Tommy Tiernan all we need to do is find out who it is we owe the money to "and shoot the fecker"
Or place all the capitalists on a rocket and sent them to another planet. If we were political informed about our real class interests instead of being tailgater of our own class enemy, we would stop paying these debts, and overthrow their stupid system immediately. We can turn money into toiltets papers, or wall decoration, and use gold and silver for cooking pots
Well, it can go on: states and corporations are immortal, they can assume the debt and let growth and inflation degrade it before making any nominal repayments. The Tories blew the gaff by making a song and dance about finally paying off the Napoleonic war bonds: debt can live for ever, ignore it.
