i meant only the similarity in timescales, not ideological - first there were marx et al intellectuals and academics, analysing what is wrong, why there is poverty and misery (or today ecological catastrophe), theoretize a counter-utopia, and only after that theoretize the ways how to get there.
hmm suppose marx thought of the methods and strategies too, like "seizing the means of production" (?).
anyway, i agree that degrowth isn't a ready program, yet, i hope.
