The culture & psychology of the large family is one where children aren't taught a sense of self, the importance of self-esteem, &/or the value of self. They are told to always put others first & themselves last. They are told that they exist as a group, never as individuals. Individuality is never valued in the large family dynamic.
Children in large families who assert a strong sense of self or individuality are derided as selfish.The concept of self is a total anathema in the large family environment. Children in large families are discouraged from becoming individuals in their own right. The large family environment discourages individuality in many forms: children must share clothes, toys, & even rooms. Personal space & privacy are non-existent in large families.

Children in large families have no ownership over their lives.They don't have anything that they can call their own. Everything they own belong to each other. The large family environment is devoid of individuality & selfhood. Parents of large families imbue their children w/the premise which is similar to communism.There is no such thing as private property in large families & children are taught that it is selfish to have & establish their individual ownership of property & individual boundaries.
Children in large families live in an institutional setting, never a private one like children in small families do. It is common for children in large families to live out in the open-being exposed to their siblings. It is also e normal for children in large families to live on atop of each other & in a crowded environment which is similar to that of institutions.
