What would cause the failure of fiat money system?

[V for Varoufakis]

The fiat system has already failed with debts that will never be paid (no country will ever be able to face the debt). The system is being kept on a fake bubble by QE and never ending printing of fake money.

Don't blame the fiat for that. Blame the banks.

True true, but thats the beauty of the fiat system.

You dont need to pay anyone back, cause why? cause its the fiat system, and its all about printing more paper until it becomes useless till we go back to bartering things forcefully.
