In Germany after WWII the economy was terrible. They printed more money but it was worth nothing. The more money you have in circulation the less its worth. It got to to the point that people would have to bring huge bags of money to buy a loaf of bread. People used the money to light fires because it was so worthless.
HOLY! Well, how about they give me one of those nifty machines. I'll just print some money for myself, and .. um.. use it to light a fire.
and it's gonna be like that again real soon.
