Now it is most important that we understand that the real reason for abandoning the regulatory enforcement of the use of the credit rating agencies is not because the credit rating agencies have been bad at what they have been doing, the subprime mortgages is a big exception of course, but the simple fact that the better they get; and therefore the more we would tend to automatically follow their opinions and the harder it would be to express contrarian views, the higher the risks that the world will encounter some systemic risks of truly catastrophic proportions. And that the regulators should have known.
