How about IVF and that it becomes almost a necessity for all their children.

Or the increased necessity of glasses at a young age.

It's not the beneficiaries particular brain that gave the competitive edge ;)

This is only an issue if everyone wants or needs kids. Glasses are similarly not a big deal. I feel like you could have used better examples to argue in favor of eugenics but at the end of the day it's still eugenics? People should have access to any and all medical advancements, better to address the problem than ignore it with selective breeding
