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.
Yes, growth in some positive sectors, but if you would agree that advertising, fossil fuels, fast fashion, car dependence, planned obsolescence, etc. all need to be severely downsized or gotten rid of, it seems like you’d agree more than disagree with the changes degrowthers want to make; that is to say nothing of their ideas of transition, which may very well be utopian. I have yet to get to that chapter in my book to make a proper investigation.
