These are difficult times for economists and company managers because the outlook for 2013 is highly dependent on how the fiscal cliff (the large government budget cuts and tax increases that take effect on January 1, 2013) impasse is resolved and secondarily on whether Europe continues to recover from the recession resulting from its fiscal and financial crisis.

Schadenfreude is the act of deriving pleasure from observing the misfortunes of others. It helps to explain our enjoyment of tragedy, comedy and reality TV.
