If you wanna see a web comic that actively calls out this kinda shit, I can't recommend 'This Isekai Maid is Starting a Union' enough.
And if you wanna see the complete opposite, try subjecting yourself to Kuma Kuma Bear, the whole thing is just the author's neoliberal power trip. It hasn't gotten to the point of slavery (yet) but apparently child labor is fair game and God really loves you only if you accumulate wealth.
I don't see why we should defederate from instances that don't speak English, if you don't want to see posts in other languages, change your settings and allow only English posts.
