I just read those two PMC pieces and I have to say I had an annoying benji smirk at all the talk about the idea of a new class being discovered in late 1970s by the Ehrenreichs and "neoconservatives" even if Press did manage to mention James Burnham at one point in a question that also involved Richard Spencer and Tucker Carlson.
Bakunin and Marx literally argued about it at the First. Michels was so fond of his iron law that he became a fascist to help implement it. Popper and Hayek independently came up with their own version of the idea in about the same year and so convinced Keynes it was one of the few things he admitted to changing his mind on. Eisenhower's "-industrial complex" speech is arguably about the emerging PMC. Just none of them discussed it in a Marxist format, especially adhering to the
Rule of Two as discovered in the prophetic visions, so the Left ignored it for decades especially when the Party Line was in force, even when Dilas wrote a book literally named it cribbing Trotsky he adhered to the rule. (Although to be fair he was largely describing the Soviet and Yugoslav experiences. And he totally was not Party Line.) "Neoconservatives" were coming into the same ideas at the same time because they were coming out of the same failure to launch that kneecapped The New Left for so long.
Also the end of that first article (chasm) was kinda wild at how many words it used to avoid saying "if not Sanders, we must get Warren" specifically. Also the multiple steps pairing down the disparate class interests and conflicts to fit into one large class with a single universal goal (shockingly "the end of human capital") was enjoyable. Was most disappointed in the lack of analysis regarding the colonialism involved in the Sanders and Warren campaigns holding events in places that once were Native American lands along with the refusal of the working class (either PMC or not) to understand their role in this continued exploitation and the necessity of immediate revolution until which they cannot be considered true allies of the actual revolutionary proletariat.
