In a paper by Joseph E. Stiglitz titled; "Towards a General Theory of Deep Downturns" [GenTheory], Joseph Stiglitz lays out what is right and what is wrong about most of current Neo-liberal (Friedmanista) and Neo-Keynesian (he calls it "New" Keynesian) thinking about current economics.
Enormous Hubris!!!
he writes:
"deep downturns have marked capitalist economies since the beginning. It took enormous hubris to believe that the economic forces which had given rise to crises in the past were either not present, or had been tamed, through sound monetary and fiscal policy."
Continuing:
"Those who attempted to defend the failed economic models and the policies which were derived from them suggested that no model could (or should) predict well a “once in a hundred year flood.” But it was not just a hundred year flood—crises have become common. It was not just something that had happened to the economy. The crisis was man‐made—created by the economic system. Clearly, something is wrong with the models." [Stiglitz GT]
