Gattaca is about human tampering of genes in attempts to create an utopia free of violence and illness. When considering the change at face value, genetically modifying people for health reasons would be very beneficial and would eliminate genetic disorders entirely. Despite the medical advantages, Gattaca's reality would divide people to a greater extent than anything prior. This dystopian society reminds me of me the books we've read before, 1984 and Brave New World, in which it leads me to wonder what other parts of life may be "perfected" by science. When considering crime rates, I don't think any changes would be made, but I do believe that "faith babies" and their parents would be more inclined towards rebelling against the system put in place.
I would definitely want to be a modified baby since there's many benefits with little downside. Although you could argue that you're "playing by the system", its still very beneficial not having to worry about illness as well as being placed highly int he social ladder. If I was a in-valid person I wouldn't go through all the trouble Vincent went through since the punishment he could've received, harsh work, and constant paranoia is not for me.
Although this movie exaggerates and plays with the topic of eugenics, it holds some truth in the idea of genetic superiority. When considering Vincent's traits against Jerome's, its clear that perfectionism is ingrained within Gattica's society. Additionally, its told throughout the movie that although Vincent can't match Jerome's swimming speed, his heart isn't as strong, and his vision wasn't as good, he is still capable of producing results and is able to get very far under his false identity. The idea of perfection is a facade which is especially prevalent when Jerome lost both his legs. Despite his intelligence and perfection (apart from his missing legs), he was thrown aside as if he could no longer be useful. Adding on, Stephen Hawking was affected by a disease in his twenties which paralyzed him indefinitely, and despite his imperfections he has made a name for himself as one of human kind's most influencial people.
