This was great, although I definitely already agreed with much of what was said!
My main takeaway is that neither 'degrowth' nor 'communism' are sufficient on their own to address planetary crisis in a just way.
A large obstacle to change is described quite well, I think, by Quinn Slobodian in various recent podcast interviews (This Machine Kills, The Dig, and others) where he talks about how workers in different sectors are pitted against each other in order to maintain the capitalist/growth status quo.
So, personally I feel like the only viable route to a degrowth communist or 'ecommunist' society is a concerted effort among union leaders and membership to take a vigorously internationalist approach.
