Plato’s Republic or Milton Friedman’s Market?, Arnold Kling asks:
I call this the Fundamental Problem of Political Economy. How do we limit the power that idiots have over us?One solution, that might be traced to the expression ‘philosopher-king’ associated with Plato, is to hand the reins of government to the best and the brightest. Since the late 19th-century, the Progressive Movement in American politics has championed this approach. The Progressive vision, which DeLong embraces, is to channel brains and technical know-how through government in order to improve people’s lives. One hundred years ago, they sought to prohibit alcohol. Today, they are going after trans fats. One hundred years ago, they favored eugenics, based on the then-new science of evolution. Today, they embrace anti-growth economic policies, based on the contemporary science of happiness. Indeed, we get headlines like ‘Tories promise to make happiness a priority’.
The other way to avoid having our lives run by idiots is to limit the power that others have over us. This is the approach that was embedded in our Constitution, before it was eviscerated by the Progressives. It is the approach for which Milton Friedman was a passionate advocate.
