In the community, the most-valued thing is "sameness". Thus, everyone strives to be the same - to not stick out. In the process of working toward "sameness", the elders at some point or another decided to give up the ability to see color (all colors are the same now) as well as most emotions, including "love", and any fluctuations in weather or climate.
In order to keep the community running smoothly, families are placed together by the powers-that-be. Marriages don't occur for love - they are arranged. Children are assigned to adoptive families, with one girl and one boy in each family. Adolescents and adults take "pills" to prevent any romantic feelings. Medication is also used to dull pain, which is seems the community hasn't figured out how to completely eradicate.
Children are raised with an emphasis on this "sameness" that is so important. They are born to women whose job it is to have children and raised in batches. Once they are assigned to families, they are given numbers and move through school with their classes. Each year, some new marker happens at graduation. Once they reach adolescence, a job is chosen for them and assigned, and they train for that job. This is the first time anything has been different between them. Prior to this, every child is treated exactly the same.
The concept of a "career" is unknown, since no one gets ahead or advances. With the exception of the leaders, no one is more important than another, and money doesn't exist. Anyone who is deemed to be "different" is "released", or killed.
