I've been pestering the economically talented people here with the "Why do we need growth?" question for a little too long to be loved. As far as I can perceive the reasoning, I understand that growth is the entire foundation that upholds the dominant economic construct... No growth, no sustainable economy. And so it seems we're stuck with not just an assumption but a necessity.

Which means that one day the current model will stop functioning (unless humanity grows itself a space ship and becomes extraterrestrial looters) or it will have to transform into an alternative form.

Is there such a thing as sustainable growth?
