It would be interesting to do an essay from a Marxist standpoint on the part played, since 1970 or so, by anti-industrial sentiments and hostility to industrial society, by doomsterism, and by general rejection of the whole idea of progress especially of the kind that are linked to technology--perspectives that at one time used be regarded as very marginal and/or reactionary by just about everyone, but which are now quite mainstream--in vitiating a broad progressive politics and taking us back to feudalism in some ways. I am working on this issue from my own point of view.
