You're right but who cares if the route isn't genetic? If parents or society at large have essentially the same negative characteristics highlighted in the film and a higher birth rate it is functionally the same outcome.

By the way, I'm not arguing for artificially controlling the birth rate or eugenics or whatever else. We need a properly-funded education system that teaches critical thinking. There is both a nature and nurture component to intelligence and related traits but we can get plenty of mileage by focusing on the nurture part.
