@Radical_EgoCom "Solidarity is based on shared collective interests."
What does "shared collective interests" mean, exactly? I'm assuming that it's not just an interest that every single individual member of the collective happens to have in common?

Nepotism is not necessarily a human universal; it is a product of hierarchical societies rather than an inherent aspect of human nature.
Regarding "shared collective interests," it is the interests that benefit the community as a whole, rather than just individual members.
