There's a way to talk about capitalism like Stardew Valley does, showing its negative and positive consequences and letting you choose your path, even if the creator is biased against it.
Then there are authors like this which are didactic and just tell you "capitalism bad feudalism good" in a narrative medium, without demonstrating how feudal society depicted here somehow makes everyone morally superior to a capitalistic society.
I'm not against politics in manga or webtoons, but I'm very much against virtue signalling.
