Let me introduce the main characters: First, the banks which are veering out of control (again!). Next, our central bankers and regulators who are doing a better job than broadly perceived; however, they lack the political support to tackle a financial system which thrives on excesses. And, just to complete the picture, we are up against a political system which is institutionally corrupt and politicians who are hopelessly narrow-minded and unable to look beyond the next election.
