Bernanke guarantees it. How did you think the Feds will pay for their massive and growing debt? This is how it works. Take a guy who makes $50k a year and has $100k in debt. He can only make minimum payments and may never pay it off. But with hyperinflation he makes $150k a year but the debt still remains at $100k, the interest rate will be higher but he'll pay it off quicker.
