Survival by its very nature is all about self interest, family interest, or national interest over that of inclusion of others.
Bullshit. It isn't a case of 'us or them'. We can survive and
so can they.
The thinking that you seem to advocate is a sort of global unity, whereupon humans come to believe that teamwork will produce better results for everyone than will self interest.
Because it will. It has in every circumstance where it's been tried. Working together
always produces better results for the group (and, by extension, the lot of its members) than does working alone in self-interest. Those who advocate for us to work in our own self-interest are the ones who don't want the group to succeed; because they profit off of its failure.
so the next question: Can global teamwork and fairness possibly help everyone better than any of us can do on our own or with our union, lobbyist,party,lawyer etc.
Your idea of fair:
Go figure!
Love your enemies!
