I mostly see it as an attempt to co-opt labor/reform movements by institutionalizing them and, while ostensibly legitimizing them, ultimately setting boundaries that view real material changes as too radical and ends up just supporting the interests of capital in an effort to manufacture the appearance of some kind of social harmony.

The only case I’ve specifically read deeply into is Austria where there’s a rich debate about whether they were “fascist” and what that means and what they were. It was several years ago and I can’t recall any names but in my initial post “austro-fascism” is a research term that’s going to get you right into the debate. Wikipedia is a reasonable place to start—iirc they were called the Fatherland Front?

Beyond that, my encounters have been more through histories that cover these periods and regimes but aren’t necessarily focus on the specific question of corporatism. Priest, Politician, Collaborator looks at Tiso, the puppet in Slovakia. Hugh Thomas’ The Spanish Civil War isn’t “about” corporatism but does discuss the ideological underpinnings of Franco and I just had a similar experience with Lisbon by Neill Lochery looking at Salazar’s corporatist beliefs weighed against the fear of invasion as a small state by its larger, nominal ideological neighbor in Spain.

The early phase of Italian fascism is worth looking into, too. The fascist manifesto was written by some modern artists and Italy remain in some ways weirdly constitutional as is synthesized Mussolini’s politics into and on top of existing political structures.
