I haven's seen it, but my guess wouold be it's quite sraightforward; the word "socialist" in the u.s. has come to label almost any government action. Now that government action is necessary it is also necessary to make the word "socialism" (in this 100% diluted sense) a respectable word.
Which is just one more indication of how irrelevant to serous radical thought is mucking about in the politics of the week. We have no impact on those politics and they are of no interest tjo us. Where do we expect to be 10 years from now? Formuylate an answer to that question, then look at the presenbt through the lens of that projection. Anything else is frou-frou.
