Personally, my theory has been that the specter of peak oil pretty clearly implies the inability of industrial economies to continue producing real wealth in the customary way. In the face of this, either consciously or at a more mystical level, the worker bees in banking recognize that, in order to maintain their villas in the Hamptons, money has to be loaned into existence some other way (than in the service of industrial productivity).
We've tried just about everything else. There was the so-called service economy, an attempt to replace manufacturing with hamburger sales. Then there was the information economy, in which work would be replaced with knowing about stuff. Then there was the tech thing, which was about bringing internet companies that existed only on the back of cocktail napkins to the initial public offering stage of capitalization -- which allowed a few-hundred-or-so thirty-year-old smoothies to retire to vineyards in the Napa Valley, while hundreds of thousands of retirees lost half the value of their investment portfolios. Then there was the housing boom, which was all about the creation of more suburban sprawl under the theory that houses (or "homes" in the jargon of the realtors) represent an obvious sort of wealth, and therefore that using houses as collateral would allow humongous sums of money to be loaned into existence -- along with massive fees for structuring the loans into bundles of bond-like thingies.
The important part of this is that the money is gone. What makes matters truly eerie is that the "bubble" in suburban houses has occurred at exactly the moment in history when the chief enabling resource for suburban life -- oil -- has entered its scarcity stage.
The logical conclusion of all this is not what the American public wants to hear: we have become a much poorer society and are now faced with the unavoidable task of making major changes in how we live. All the three-card-monte moves at the highest level of finance lately amount to an effort to avoid the unavoidable, acknowledging our losses. Certainly the political fallout of all this will be awesome. But it's not about politics, really. It's about the entire society's inability to form a workable new consensus of reality."
