I see your points, however this is mostly US-centric problems, and the FED is doing a lot to change the sentiment. US problems do effect the rest of the world, I believe a slow down will happen but not to the extent of "death-too-everything" that mega-bears are predicting. I also think that a housing rescue package by the fed is also in the works. and will come out soon, they just want to get the speculative froth out of the system, and for a bit of suffering, back to reality to accur.
good businesses will be profitable and make good long term growth investments.
I am not a day-trader I am an investor and invest as Buffett says, I could be quite happy if the stockmarket was closed for 10 years.
