By coincidence the Euphoria series finale just aired, and there's a relevant bit of text in the Guardian's review:..
Beyond the distracting shootouts and drug cartel wars, season three of Euphoria was at its strongest when it reflected the increasingly nihilistic world young people are consuming online, where they’re being raised to believe that they either have to be the hunter or the prey. As the show ends with the American flag rippling in the wind, I was reminded of Trick Mirror – a 2019 book of essays by Jia Tolentino, where she argues that scamming is becoming central to American life. Tolentino writes that to be American is to learn that “one of the best bids a person can make for financial safety” is to get “really good at exploiting other people”.
In other words, this manga is more than just a toxic relationship, it's the entire streaming ecosystem, globally.
