'Nations have reached a “Keynesian endpoint”'

My, how times have changed:

Debt-fueled spending programs aimed at combating the global financial crisis of 2008 are among policy tools now "being seen as a magic elixir that has morphed into poison."

While I tend to agree with Jeffrey Sachs' central thesis about a misguided Keynesian response to economic crisis, we've seen pronouncements about the death of various schools of economic thought before. 

And while I think he paints with an overly broad and partisan brush, I think Derek Thompson at The Atlantic makes a solid point - Sachs, as he expands his argument, is arguably trying to have his cake and eat it too.
