However, I would more eagerly buy comparing such rituals to human tribal social customs. It's problematic in modern life.
Advertising and employers try to link into our tribal social instincts to create false sense of loyalty to either their brand or the company one works for. "Family" is the most over used word now and it's in danger of becoming meaningless or even a caricature of itself.
Tribes were based family or marriage ties usually and provided an expectation that if one fulfilled what the tribe needed and expected from them, then the tribe would take care of them and protect them.
In modern life, no such real assurance exists, though we're often encouraged to delude ourselves that it does. We live in a world filled with strangers who compete with us for resources and jobs. Employers can and will lay a hard working, loyal employee off. A spouse maybe divorced at will upon a whim. Families can disinherit and disown at will on whim.
