I have seen a few of these with similar story lines and realized we are living it right now. They have the best healthcare, the best food, the best everything and most of us are a few dollars from disaster. That scares some of us to death literally from all the stress it causes.
It also makes it ‘safe’ to discuss controversial topics, because it’s ‘only scifi’ (or horror/fantasy).
Allows creators and authors to fly under the radar with stuff that could potentially get you arrested, censored, cause controversy or end your career. Prime example, Tarkovski movies like Solaris or Stalker, which are full of religious metaphors, despite being released in the USSR.
