[Vision2020] Why are we bailing out all these large corporations?

[Paul Rumelhart]

If a large corporation is about to go bankrupt because they loaned money 
without proper collateral behind it and without a determination that the 
person taking out the loan could reasonably pay it back, shouldn't we 
let it crash and burn?  Isn't that what is so casually referred to as a 
"market correction"?

I've heard it stated that there is something different about this 
situation - it's more dire and it could have a snowball effect on the 
rest of the economy or even the globe.  Does anyone here know enough 
about this to explain that?

What is so important about this situation that would result in the 
necessity for an Iraq War-sized expenditure?

Or is it a case of the rich looking out for the rich, which I'm 
half-tempted to believe is the case.
