I'm just gonna deal with the flaw in understanding you seem to have about banks:
Oh goodie.
Banks exist to make they're account holders and stock holders money. Not to fund some nutjob social scheme.
I assume the following story will tell me how these banks did this to make money and not out of some social scheme. This was a good preface so I can tell.
Banks make loans because you sign a contract with them saying that you'll pay the loaned amount plus some agreed upon amount above the loaned amount as a fee for receiving the loan.
I'm glad you explained the concept of a loan to me.
The situation we have was precipitate, at least in part, by politicians deciding that it would be good for they're political fortunes for they're constituents to have access to affordable housing. That's a good thought, admirable thought, one that deserves examination. The problem stems from the fact that you have people who understand less about how good fiscal management than I understand about attracting a female. They released the reins and the horse took off and for a while it was a great ride, but horse has tried to jump a ravine that was too wide and now we're stuck with a lamed up horse and no one wants to put it out of it's misery.
So who's the one with bad fiscal policy? The banks or the politicians? Because I have yet to see anyone tell me how these banks were FORCED to give these loans out, forced to ignore salary levels and credit checks and forced to engage in any of this activity.
"The stupid politicians made it easier for banks to give out stupid loans!"
Using less anologies, a person who makes $30,000 at the hairdressers with 3 kids and no savings has ABSOLUTELY no business buying a house worth 3 times they're annual income much less 10 times, like they were doing at the peak of the bubble. It's like asking the gangster to leave your incisors in when he beats you to a pulp for reneging on a deal. Nothing but trouble.
So why did the banks give the loan? Banks can't reject loan applications based on ability to pay?
Let me see if I get this right.....
Politicians, in an effort to garner votes among the poor (people would be using these loans to buy homes) passed laws forcing banks to give loans to people who couldn't possibly pay them back. Banks, knowing they had zero say in the matter, gave out these loans they knew couldn't be paid back. They then sold those loans to other institutions, earning a nice fee.
And it's NOT
Banks use relaxed lending laws to give massive amounts of credit to people who couldn't get it before in an effort to get in on the giant rise in housing prices?
Really? People were (and are) getting huge loans and giant lines of credit because the government made them do it? These poor defenseless banks didn't have a say in the process that made them crazy rich until it all fell apart and we needed people to blame?
