The problem is that liberals tend to affiliate themselves with Harvard types, and Harvard types believe that they are smarter than markets. And, at this moment in history, the Harvard narrative is that the financial crisis was caused because of blind faith in markets regulating themselves. According to this narrative, the election was a mandate to Harvard to deal with huge market failures in finance, health care, aggregate demand (hence the stimulus), and climate/energy. Based on this narrative, Harvard is absolutely committed to expert control over the economy, liberaltarians be damned.
But the Harvard narrative is gauche. People can learn to have better taste if someone shows them how. More generally, you can’t expect a way of thinking to become popular with the elite if you concede from the outset that it appeals primarily to losers. Anyway, yes, high school never ends.
