This may not be the case here, but I have noticed that there is a specific subset of embittered marxists (?) who believe that work is strictly either back-breaking and life-ruining, or “not real work”.
The way it was explained to me once is that you’re either selling your body or your brain, and selling your brain pretty much automatically makes you “small bourgeois” (because you’re like the modern equivalent of a 19th century artisan) which is a social class supposedly directly opposed to the proletariat.
I think it’s a fundamental mistake to try to fit a modern social class/role that didn’t exist in Marx’s time through a 19th century lens and that trying to make a hierarchy of working classes is wrong, but it’s an interesting perspective nonetheless that at least explains some of the discourse we see in threads like this.
