But...they are (or, rather, they can reasonably be expected to produce genetic changes which reinforce themselves.) Because cultural changes effect mate selection, and also otherwise improve the relative fitness of those naturally inclined to thrive in the cultural environment.

Most people who obsess over celebrities, or fall for every ad they see, or whatever else Idiocracy thinks is the downfall of society, aren't mentally impaired. They were raised in a society that discourages critical thinking skills and devalues education. They're ignorant, in other words. You don't fix ignorance with eugenics. You fix it with education.
