We have had many and famous dystopias in the mass media for many decades; but most of the most popular of these have included a 'happy ending' whereby the controlling baddies (those who make and serve the oppressive System) are overthrown, and replaced by some-thing apparently much better.
Typically, this is narratively possible because in these dystopias there are relatively few baddies oppressing a mass majority of decent people - and the badness has a focus which can be attacked and beaten.
What we have not seen is a dystopia corresponding to the one that we have here-and-now; and that is because this is an End Times dystopia based-upon a very pervasive value-inversion that afflicts the mass majority almost as much as it affects their more-overtly-evil oppressors.
(By Biblical analogy: this is an Antichrist dystopia.)
In other words - we have a majority of baddies: that is, a majority of people on the side of evil, or at least collaborating with evil; and doing-so because they believe that their evil is good (and that good is evil).
(This works by the multiplicity of Litmus Test issues - supporting any one of which brings an individual or institution onto the side of evil - sooner or later.)
Thus, the masses do not want the oppressive System to be overthrown - but instead reformed, made nicer and kinder.
Furthermore (and because of our evil being pervasive, endemic) is that there is no focus to evil in 2021; at least, not the kind of focus that can be fought, overthrown, and replaced with the modern equivalent of a Good King.
Modern evil is bureaucratic; the baddies now consist of multiple intersecting and overlapping committees. No individual is essential, and probably the top dozen, score, hundred or even thousand baddest-of-baddies worldwide could be eliminated without provoking more than a hiccup of The System.
All of which makes it apparently impossible to do the trick of imagining an analogous dystopia to this one; and then imagining a way in which is could plausibly and helpfully be overthrown.
Maybe it is not impossible to do this imaginative and creative feat? But I haven't yet seen anyone succeed; indeed I haven't seen anyone even try...
