I've read an awful lot about the peak oil phenomenon, and what I've learned has convinced me that a continued cheap supply of oil is, as of 2006, no longer certain. To date, he world has not matched the production capacity of that year. This is due to actual on-the-ground causes (the crashing of several supergiant fields, political instability and violence, and countries keeping more of their decreasing production for their own populations and thus exporting less), and not simply greed. A report put out last year, subsequently buried, by the Dept of Energy confirmed as much. Combine those rather poor prospects with the whole mortgage crises (and they are related), and you're going to get some serious madness in the financial sector; like people doing everything they can to fuck the world to make a buck. Nothing new there, though.
