Source for thinking the degrowth crowd thinks this: Introduction to “The Future is Degrowth”. Does the degrowth crowd really think they can get rid of capitalism without any violence? This seems to have the opposite of a historical precedent, and is a deviation in Marxism, which they seem to heavily draw from. Anytime revolutionaries took the peaceful road they got outcompeted at best and massacred at worst.
I don’t think degrowth is the answer, but it depends on your definition of degrowth. Growth using green technology and renewable energy backed by socialist economic planning should be the solution.
My degrowth position is basically: you can’t have infinite growth on a finite planet. We use way more resources than we actually have. Under socialism we can make far fewer products, but make them higher quality, so fewer resources are wasted. We also need a circular and library economy where things are used as much and by as many people as possible within a closed system rather than producing things for profit.
Really I can’t wait to see what a modern, technologically advanced socialist economy comes up with in the field of technology. Just hope we live to see it
