agip, it's a complex problem with no easy answer, but the net of culpability can be cast far and wide. The Federal Reserve is one of the main culprits, because of their constant tinkering with the price and availability of credit, thereby obfuscating transparency. The GSEs get their fair share, because, even as they didn't necessarily hold sup-prime mortgages per se, they also distorted the availability and price of credit and were levered at 50-1, compared to the banks at 30-1.
What's ironic is that, as much blame as Greenspan (and Bernanke) deserve for creating bubbles that pop by not restricting margin and then having to reinflate them, Greenspan was the only one pounding the table for Congress to rein in Fannie and Freddie and to get its own fiscal house in order, including entitlement restructuring. Go back and read the semi-annual testimony from those days. It's all in there. I knew when Fannie had to restate four years of earnings circa 2000, costing Franklin Raines his job, that that was only the first cockroach and more would be coming.
The government also chartered only three "legitimate" ratings agencies, with S&P being the primary caretaker, thereby creating a ratings cartel and eliminating competition to rate debt accurately, setting up conditions ripe for nepotism. Then there's the good old SEC that missed all of this, despite the fact that Sarbanes-Oxley was supposed to prevent a massive crisis like this in the wake of Enron, especially after Clinton repealed Glass-Steagall. The government also made a huge mistake in finding a suitor for Bear, creating moral hazard for Lehman, and picking winners and losers.
While, no doubt, predatory lending existed, very few people are really "victims" here. Most either were reaching for too much house they knew they couldn't afford or buying rentals on the cheap, hoping to become real estate tycoons. Again, if credit wasn't so widely available and cheap or loan-to-value ratios were required to have a basis in reality, we wouldn't be here. I can recall a piece in the L.A. Times interviewing people who were purchasing 600,000 houses on very low income. When asked why, the typical response was because the homes would appreciate $200,000 over the next year. Again, simple greed. Not everyone can afford a home, and social engineering will never change that simple fact, only exacerbate problems in the long run.
I would even go so far as to say that the mortgage interest deduction added to price inflation in the housing market, though it took decades to build up. We need serious tax reform in so many ways. This push for the "American Dream" that's led to suburban blight has made us susceptible to the perfect economic storm and created many of the social ills prevalent today rooted in jealousy, the ego, me-first, keep-up-with-the-Joneses attitude, divorce, cultural depravity, etc. "Dream" is and always was the operative word. Even our poor, which need some kind of a safety net insomuch as it doesn't foster total disincentive, live better than 90% of the world, which is rapidly trying to catch up and achieve our "lifestyle."
Now, while financial engineering and CDS aren't evil in and amongst themselves, there's no doubt that many of these banksters spliced, diced, and repackaged crap, sold it off, and took the other side of the bet. On the other hand, those buying specific tranches of the debt knew or should have known the risk involved when buying a specific, risky tranche, such as a Z-tranche. Again, they were reaching for yield. I have friends who worked for some firms repackaging debt and not taking the other side, working under the assumption that the credit agencies had rated the loans properly. The biggest problem is that these CDS were never traded on a third-party exchange with a transparent clearing house, not the CDS themselves. And while I understand why some in the industry would adequately oppose just such an exchange, I think it is necessary.
At the end of the day, I liken it to a campfire. The government set up the firepit and kindling, complete with lighter fluid, greed amongst individuals and predatory lenders lit the match, and the big banks poured gasoline all over it, starting a forest fire. Fannie and Freddie are paying exorbitant bonuses, but still have their hands out for more taxpayer money. They should've been nationalized and/or shuttered. The big banks should've been allowed to fail or take massive haircuts and the debt should've been restructured properly, but it still exists in the form of Enronesque off-balance sheet entities. And Ginnie is still subsidizing FHA loans. The circus plays on.
Here's a decent take on why Wall Street doesn't deserve all of thge vilification it's getting and, as a I said before, we have strange bedfellows in Washington. That's where much of the protesting should be. Just look at the pie chart, if nothing else, but it's a short article.
