In the Movie Gattaca are the parents allowed to pick traits of their babies?

In the movie Gattaca the parents are allowed to pick the traits of there children. The reason for this is that they wanted to create the perfect human so everyone could be the same and live up to being perfect. The world should not be allowed to do this because it would change the world and the way people see it as we know it. Everyone in the world would be the same and who wants to be the same as other, everyone likes to be consider unique and have different potential then others. That's why alot of people have different ideas than one other that's why the world technology is growing because one person created a better and more efficient invention than another. The world should be able to let parents have natural birth and not want to chose the children's future before the children even is born. The parents should love their children regardless of their flaws.
