A bunch of my friends are traders, and it seems that the consensus right now is that as far as the stock market is concerned, nobody knows where this is going (either way), and is scared to take any real position (that's why volatility has been up lately, volumes are down (and not just because it's August).
My take is that we're most likely headed for a period of Japan-like stagnation. There are huge structural employment issues in developed countries to take care of, properties are likely very much underwater for many homeowners that do still have jobs in the US, and governments are taking the knee-jerk reaction to the stimulus needed in 08/09 by introducing austerity measures, which will only serve to slow the economy further than it is at the moment. The debt levels in developed economies are still waaay too high, but there is a very real risk of taking the crutches away before the economy can walk again (hence Bernanke returning to easing measures: he sees the writing on the wall).
So, while governments worldwide go about trying to tackle the debt problem, growth will slow and there will be little job creation in many sectors. But the real change has to come from the people learning that, fundamentally, they can only spend what they earn, and that debt is not a bottomless pit.
