Maybe the bears like Roubini and Meredith Whitney are right. Maybe not. But have a look at some great stuff from the great Tom Barnett that may inform your analysis:
I made a decision a long time ago not to make my career a bet on bad things happening. I think that approach simply corrodes your strategic thought capacity. Human history is progress, so if you're constantly having to screen out the good to spot the bad, your vision will unduly narrow. If you bet on progress, you can easily contextualize the bad, because progress is never linear. But if you bet on retreat, you must consistently discount advances as "illusions" and "buying time" and so on, and after a while, you're just this broken clock who's dead-on twice a day.
