We have a melt down in dual bubbles:
A) credit. Housing is just one of the effects. Massive amounts of sketchy derivatives are an even larger problem.
B) commodities. This melt down won't precede an econ slowdown, but will happen during a bad recession.
Regardless of the public, this is going to be long and hard. No amt of liquidity can bail out solvency problems. the Gov will eventually get involved in a big way bailing out all sorts of shit (assuming they even can). A FED just stepping aside would accelerate the pain, but get it over with.
