Patriotism is an emotional attachment to a nation which an individual recognizes as their homeland.
That is description from Wikipedia and I think it is safe to say that universally all countries in the world trying to create their patriotic agendas. Sometimes it seems natural as it is with deep roots in history, culture. Sometimes it looks very like a ”project”,especially for relatively new countries. I am wondering, is there fundamental economical reasoning for that? For example, patriotism can lower cost of armies that in one or other history moment helps for country to survive or helps to create more stable economical system and so on.
Is there any research made in economical reasoning for patriotism? If anyone could give any links to articles or books or just give insights what is economical reasoning for patriotism (if there is one).
