(Warning: this entry contains gross imagery.)
We see this kind of story fairly often:
First the author postulates a future development that's so awful that in real life, American society simply wouldn't stand for it; and then the author complains (by telling the story) about how awful it is. It's like saying, "In the future, all babies will be tortured and then murdered. OMG! That's awful! Think of the children! Something should be done to save all those tortured and murdered babies!"
The first step that we're being asked to believe is too wildly implausible to believe. But even if we did believe it, we already agree that it's awful. So why bother reading--or writing--the story?
The most common version of this story is the future-of-punishment story. We get a lot of those, though not nearly as many since we added it to our stories-we've-seen-too-often list. In such a story, the author postulates that in the future, punishment is handled differently; for example (which I just made up), in the future, all people who are accused of crimes are required by law to gouge their own eyeballs out with plastic sporks, and then to eat the eyeballs. The point of the story seems to be that it's truly awful that all prisoners have such a horrible thing done to them as an official part of the criminal justice system--but since in the real world, that particular horrible thing is not in fact done to them, and I can't imagine the American criminal justice system changing in such a way that that particular horrible thing would be done to them, the story isn't very effective for me.
Of course, someone could write such a story as a way to comment on our current criminal justice system, effectively saying "the way things are in the real world is actually pretty barbaric, and something should be done about it." There's a long tradition of such stories in sf. I personally have very little interest in reading or publishing that kind of exaggeration-of-real-world-ills story, because it's usually a very heavy-handed polemic presenting the author's worldview, and I dislike heavy-handedness in fiction regardless of whether I share the author's worldview. But at least I could see the point of writing such a story.
But most of the future-of-evilness stories we see (including most of the future-of-punishment stories) don't appear to be intended as social commentary; they're just showing a made-up exaggeratedly (and implausibly) bad situation and then lamenting about how bad that situation is. Which ends up reading to me like the author is saying "Look at this awful thing I made up! It sure is impressively awful, isn't it?"
