Neoliberal Professor J.Bradford DeLong admits that deregulation of the financial sector during the 1990's was a bad idea.
An excerpt: "It may even be the case that we ought to return to the much more tightly regulated financial system of the first post-World War II generation. That system served the industrial core well, at least as far as we can tell from the macroeconomic aggregates. We know for certain that our more recent system has not".
It is amazing that the word 'may' is included in the above excerpt and not the word "should'.
