Growthmania in a finite planet is just a stupid idea to enrich the rich and to create the biggest social and environmental planetary risks in human history. Growthmania is behind the worst decisions that are being made by blind people around the world. While Central Banks, governments, pundits and greed economists are just thinking about growth after growth in all economies, scientists are calling for absolute reduction of our use of matter and energy to avoid life extinction and collapse. But this is too much for a greed man like M.E.Erian to understand. The same applies for all economists like Paul Krugman and Joseph Stiglitz that still believe Nature is a subsystem of the economic system and therefore our global economy can be bigger than the planet. These poor men still believe Nature and ecological services are irrelevant for the economic process and can be replaced by capital produced by men. And so on. The list of conceptual mistakes is enormous. But as Kenneth Boulding once said "Anyone who believes in indefinite growth in anything physical, on a physically finite planet, is either mad or an economist."
