I suggest the inciting incident should be toward the front of the logline, not buried at the end.
I have a question:? what is the "official" justification in this story world of yours for? needing to kill off non-likeables?? What motivates the powers-that-be in your story world to resort to this culling of losers??? What "threat" do the losers in this story world pose to the established order that the ruling order uses to justify this termination policy?
Stalin and Mao didn't just purge -- murder-- tens of millions of innocent people; they also manufactured an official reason why they had to do it, (Their victims were counter-revolutionaries, covert capitalists, enemies of the people, traitors, etc.)
In every story world, there needs to be a "rational reason" for the irrational and unjust rules of the dominant order.? Like in the movie, I just loglined, "Equals" where human emotion is treated as pathological disease and love is punishable by death.? Why? Because emotion is the source of evil, of social strife and war. Hence, from birth all humans are subject to doses of drugs that "cure" humans of their emotions so there can be a collective utopia of peace, social cohesion and productivity.
How does failing to live up to minimum "likeability" standards pose a threat to the crime-free world of the story world?? (I can see them being banned from the internet, their cell phones confiscated -- but killed?)
As I said, I find the premise interesting, but I haven't (yet) been able to suspend disbelief and buy into the story world.
