Doesn't seem perplexing to me either. Humans are tribal and their survival depends on teamwork of about ~100 people or so. This is natural on intimate scale.
What perplexing is to think about how humans can cooperate effectively on a scale of billion people to solve humanity biggest problems.
As we can see, empathy for humans outside of the tribe is limited and so different gangs fight each other, let alone different countries.
Maybe we can think about techniques to create empathy among strangers.
