I don't think there will be a 2nd crash, THIS IS IT BABY!!. This is just the beggining. I think before Obama's first term is up we will have the SHTF, that we all have been talking about.
All we would need is another oil spike, with 3 0r 4 dollar gas, and that would be the nail in the coffin for the consumer.
Like Noworries said
1) price controls;
2) soup kitchens;
3) unemployment over 15%;
4) massive cuts in defence spending (and corresponding geopolitical instability);
5) dollar collapse? (ie--depreciation of 30-50%).
