Back in the day, more children meant more wealth and prosperity for the family. More friends meant more support, bigger communities were stronger against others. It was need based, as they have a need to support and survive by themselves.

The nation concept now drains out the need and viability of communities, families and friendships. It's like a whale swallowing animals. Animals can no longer keep their own structure and identity once they are inside the whale. They will be disintegrated into individual molecules and become citizens of the whale. Nations do the same. The existence and strength of a nation requires disintegration of internal structures and autonomous bodies. Communities, families and friendships all go against the individualistic nation concept. The best citizens are individual workers with no connections and no opinions and maybe no gender.
