OK, I hope my question doesn’t get misunderstood, I can see how that could happen.
Just a product of overthinking.
Idea is that we can live fairly easily even with some diseases/disorders which could be-life threatening. Many of these are hereditary.
Since modern medicine increases our survival capabilities, the “weaker” individuals can also survive and have offsprings that could potentially inherit these weaknesses, and as this continues it could perhaps leave nearly all people suffering from such conditions further into future.
Does that sound like a realistic scenario? (Assuming we don’t destroy ourselves along with the environment first…)
I think the point Idiocracy was trying to convey had less to do with the genetics of the stupid people breeding, and more so the downward spiral of intelligence due to policy societal and governmental changes. Dumb people, make dumb policy choices, including with regard to education. To me, it stands to reason that the downward slope of intelligence is percitpitated on how effective governmental policy is and how well education is distributed.
