The business of investment for at least the past four years has been akin to conducting a detective inquiry: whodunit? Just how did we end up in this mess ? To tackle one's enemy, one first needs to identify it. In the popular conception, a myth gleefully adopted by politicians, it is all down to corrupt American investment banks, poisoning the collective well of global capital with subprime mortgage filth - what Professor Robert Vambery in this week's Economist nicely if grimly refers to as adding three quarts of milk to a quart of sewage and creating four quarts of sewage in the process. And then the poison spread. It is a neat little tale but nowhere near sufficient to explain the extent of our current malaise. We can throw some mud in the direction of politicians, but that is a little like shooting the messenger; they have only been dispensing the bread and circuses and pension and welfare benefits on the never-never that everybody has been clamouring for. The culprit we find the most culpable, and which draws all these disparate threads of blame into one cohesive narrative, is a fundamentally corrupt money system.
