By moving the setting to an unfamiliar one, you can make parallels to back to _familiar_ societies in a way that allows the audience to see them with a new eye. It's a nice trick to get around familiarity blindness and sidestep some biases.
"Gee, the apparent pointlessness of these jobs sure is dystopic, huh?" pauses, stares significantly straight at the audience
"Turning every little thing into a carefully-metered financial transaction sure is dystopic, huh?" pauses, stares at audience
"These screen-centric disconnected lives sure are dystopic, huh?" stares at audience
"Really horrible how they shit on the infirm or those who otherwise fall out of society and don't take their pointless jobs seriously enough, huh? I mean, what an awful system, right? Why, this is so obviously terrible and evil that it'd never exist in real life, in such a blatant way. Just ridiculous." stares at audience, judging them
"Amazing how this society's mass media so effectively and complete captures and commercializes dissent, isn't it? How awful!" stares at audience
"All these people could have just left and gone off into the forest instead of participating in, being ground down by, or willfully perpetuating this nonsense, and didn't just because that's scary and unfamiliar? What kind of cowards and/or monsters must these people be?" stares loooooong and hard at the audience
All hail the hypnotoad!
