Kicking the Snowball Down the Road

"The saying of course says "kicking the can down the road", and we see it used a lot when referring to the financial crisis and the reactions to that crisis from governments and central banks. It's a pretty good metaphor as metaphors go, but I don't think it's perfect; it doesn't paint the whole picture. A can that gets kicked doesn't change much. The financial crisis does change, however; it gets bigger as we go along. A snowball fits that picture much better."
