Here's a comment I found with a bit more detail on the point about corporatism and no glib remarks about the working class:
'a lot of English speakers don’t know that in Italian corporazione doesn’t mean “corporation” in our sense of the word — it was the word used for the old craft guilds. Mussolini borrowed a lot of ideas from the movement called guild socialism. He also forced binding arbitration on wage negotiations and forced businesses to pay their employees more — that was one of the reasons he was so successful until he made the stupid decision to go to war. The confusion between fascism and neoliberal capitalism is a very popular bit of rhetoric on the far left, but it misses a lot of what the fascist movement was up to — and a lot of the reasons why it was so popular in its day.' - https://www.ecosophia.net/the-revolt-of-the-imagination-part-one-notes-on-belbury-syndrome/#comment-78069
Is he wrong?
