Yes, Alan Greenspan is still around. He tells us that he predicted that there would be a crash and that there will be another. If he predicted it then he should have done a lot more to manage it, otherwise, given his position, his “prediction” is facile. Saying there will be another is as helpful as saying there have been financial crises in the past.
What is required is suggestions on how to develop the financial system so that it works better. And that means extinguishing moral hazard from the system. And that means cultural maturity as much as regulatory or technological development. We need new thinking.
