Degrowth is a noble ideal to strive for, and it would certainly mitigate a lot of our current problems if implemented. However, I fear that it is an ideal that can be adopted by the few but not the many. Growth, progress and personal ambition are inherent human traits - it may not be the case for all people, but it is certainly evident in today’s society and many societies that have come before. In my opinion, we need solutions and frameworks that most (if not all) personalities can exist within. I worry degrowth is wishful thinking, and would love to hear your thoughts.
All of that said - I believe it is a very worthwhile thought exercise and even if all degrowth principles cannot be implemented, some can and that is what matters.
I agree that in the long run degrowth is not compatible with capitalism, at least not capitalism as we know it. Even if markets and private property continued to play some role in the economy. However, I think it’s important to emphasize that we don’t need to first somehow completely rid of capitalism (that would require some higher order magic) and then implement degrowth. There are many reforms that can start building the path of a prosperously degrowing society. A good overlook of degrowth policies can be found in this article. Of course, the need to reduce material flows is absolutely urgent, and I definitely advocate building popular support and implementing degrowth policies asap.
I read the article you linked but I don’t see how it backs your argument that degrowth could be compatible with some form of capitalism (as you mention in your first sentence). It seems to me this article does the opposite.
Personally, I can’t think of any kind of capitalism that is compatible with policies / goals / objectives related to:
or
or
or
etc
(found in the Appendix A. Thematic synthesis of degrowth policy proposals)
For me degrowth is potentially one way to get rid of capitalism.
