Yeah and then it's a domino effect:

Companies are undervalued, resulting in depreciated retirement portfolios, causing more economic woes, throwing the remainder of the market into a panic and a sell off, resulting in a dollar that worth about as much as a quarter, causing basic living expenses (food, heat, etc) to go through the roof, which in turn results in hoarding/chaos/social disruption, which finally ends in us changing the name of our country to the United States of Greece.
