I think you guys are too pessimistic about the world economy.
There are problems with financial system around the world but I think the governments of major countries can work together to get these probelms resolved soon.
A reccession like 1929 will not happen. At that time, US is a single country trying to resolve its problem; but now almost all the governments around the world can work together to get these problems done. For example, China has huge amount of dollars and they will inject the money into US financial system.
I don't think the sky will collapse. The run will rise as usual tomorrow.
