Utopian societies are supposed to be perfect. No crime. No difficult choices. Paradise, right? That's never how it works out. Utopian societies are always a dystopia to someone, and the someones in this case are the lower classes. Even if it weren't for the skyrocketing oil costs and rampant poverty, Lena would still have plenty to be dissatisfied about. Her whole life is decided for her, and so her life is completely devoid of surprises. All she has to look forward to is going to a boring school. Then having a boring job. Then having a boring husband. When Lena realizes that this complete lack of free will just isn't for her, she decides that something has to change.
