This is a recession we have to have eventually. The longer we delay it with cheap easy credit, the worse it will become. It is simply trying to solve the problems of regulation with more regulation.
The reasons why we ended up here make up a totally different story though. This is where people may disagree with me, as socialists hope this is the 'failure of capitalism' they can refer to after years of ridicule after the Soviet Union collapsed, but I believe it was because of the compassionate, although misguided, government intervention that initially guaranteed the loans that firms like Freddie Mac and Fannie Mae were giving out.
They thought they'd make housing loans more accessible to the poor. What they ended up doing was incentivising a build up of junk loans. Now the taxpayer must pay for a relationship between government and corporations that went wrong. The market certainly doesn't want to buy these junk bonds, so the right now the proposed "solution" is to price-fix at the tax-payers expense. We, the taxpayers, will buy them.
