If there is anyone to hold accountable, it is Congress (although not just them).
As for the money, it has gone to money heaven, and we'll never see it again.
The stupid borrowers have no money and in many cases never did. You CAN'T get money from them. The problem was loaning money to them in the first place.
The banks, while undeniably stupid, can at least point to laws passed by Congress that pretty much required them to exercise affirmative action in lending.
Coupled with that, deregulation, while normally a good thing, made banks into their own oversight. With money on the line, this was very bad move. Seperation of power applies to banks as well as it does to political power, for similar reasons.
So....
#1
Scrap any affirmative action style lending laws.
#2
Even some modest oversight of lending practices, and oversight NOT controlled by the banks (seperation of power), would do a world of good.
#3
Stop whining, and get on with our lives. The money is gone, NOT stolen, NOT hoarded somewhere. It is simply dead and gone. It cannot be 'recovered'. (but hard workers that actualy produce wealth can create new wealth, if we let them....)
deal with it.
