I think you and I remember that scene differently. The example "intelligent" couple put off having children to focus on career goals, when they finally decided to go for it and had fertility issues, they were significantly older than when the scene began.
Loss of reproductive functions happens naturally with age, which is why humans have a so-called biological clock. That metaphorical bell rings when you're at your biological peak for creating offspring.
The simpletons in the example, being driven more by biological needs and fleeting desires. So they had children without regard to whether they could afford to or with any planning or foresight.
The intellectuals on the other hand were waiting for the right time, which, by the time that happened, fertility had dropped to the point where it wasn't going to happen.
That's what I understood from it, but idk. I'm just some guy
It's only eugenics if the solution is to interfere with human reproduction. The movie is about an average person living in a stupid world. Not a call to euthanize useless eaters.
Lets see if you can propose a different 2 minute introduction that allows the same world building but satisfies your sensibilities. I suspect you won't be able to beat the directors choice.
Not really a turn around. I'm demonstrating how the details of the first 2 minutes are inconsequential to the rest of the film.
If those 2 minutes offend you, skip them, invent your own opening and enjoy a hilarious comedy that makes no further comment on the fact that richer, better educated couples statistically have less children.
"Critics note Vining's involvement with the white supremacist journal Mankind Quarterly and his acceptance of grants from the Pioneer Fund."
And
"Some studies nonetheless claim to show no evidence for dysgenic effects in human populations.[47][48][49][50] Theories about dysgenic and eugenic effects in human populations have historically been associated with scientific racism."
Well well well, I'm not subscribed to Mankind Quarterly, but I would like you to know that before the industrial revolution my ancestors (and probably those from everyone reading here) were working them fields and couldn't read, so let the rednecks reproduce, we'll be fine. Thank you for coming to my TED talk.
