What happened during the last crisis is also a great illustration - many banks took taxpayers money during the 'dark hours' then paid it back easily some time later, when the air cleared. Some went as far as to suggest it wasn't necessary at all. Well, the truth is, the banking system as we know it survived only thanks to governments stepping in - otherwise none of the banks we know would exist today. There was 0 trust during the crisis - and all the banking system is build on trust.
That's why the FED is "taking a sledgehammer to squash a bug". That's also why it's a very disturbing signal. My gut tells me shit is about to hit the fan.
PS. But don't try to time the market and short it - as the saying goes, the market can stay irrational longer than you can remain solvent.
