Everything you know about traditional economics is wrong. Dead wrong, says MarketWatch's Paul Farrell. Why? Because it's all based on the absurd Myth of Perpetual Growth - endless growth, ad infinitum, forever, till the end of time. That's hard to justify on a planet of finite resources. Eventually, the view of traditional economists will be superseded by the eco-economist and a world of no-growth economics, but, Farrell says, it won't come without a collapse first.
