Reminds me of "The Disappearance of Rituals", by Byung-Chul Han.

In this book he says the disappearance of rituals is due to the weakening of the communities and the isolation of individuals. It's not uncommon, specially in big cities, neighbors that are strangers to one another living inches from each other. Without a community to validate your rites of passage, what's the point of having rites of passage?

Byung-Chul Han has lots of interesting insights and is a prolific author. Give it a try. He is most known for his book titled "Burnout society".
