WE are prisoners of the metaphors we use, even when they are wildly misleading. Consider how political candidates talk about the economy. Last month President Obama praised immigrants as “the greatest economic engine the world has ever known.” Mitt Romney says that extending the Bush-era tax cuts will “fuel” a recovery. Others fear a “stall” in job growth.

Call it the “Machinebrain” picture of the world: markets are perfectly efficient, humans perfectly rational, incentives perfectly clear and outcomes perfectly appropriate. From this a series of other truths necessarily follows: regulation and taxes are inherently regrettable because they impede the machine’s optimal workings. Government fiscal stimulus is wasteful. The rich by definition deserve to be so and the poor as well.

This self-enclosed metaphor is the gospel of market fundamentalists. But there is simply no evidence for it. Empirically, trickle-down economics has failed. Tax cuts for the rich have never once yielded more net revenue for the country. The 2008 crash and the Great Recession prove irrefutably how inefficient and irrational markets truly are.

What we require now is a new framework for thinking and talking about the economy, grounded in modern understandings of how things actually work. Economies, as social scientists now understand, aren’t simple, linear and predictable, but complex, nonlinear and ecosystemic. An economy isn’t a machine; it’s a garden. It can be fruitful if well tended, but will be overrun by noxious weeds if not.
