http://en.wikipedia.org/wiki/Tragedy_of_the_commonsindividuals acting independently and rationally according to each one's self-interest, behave contrary to the whole group's long-term best interests by depleting some common resource.
'Individuals' can be replaced with 'nations'. Military budgets, geopolitics and trading limits are a massive burden on the global economy. If there were no nationalistic nations then we'd already have a much higher standard living for anyone.
And that's just the direct benefit. Nationalism also misdirects masses. It allows the public to be distracted with artificial scape-goats to steer them away from the actual culprits.
exactly, there are national interests (that I don't understand), Corporate Interests (that I defend), and what about
People Interest? It so sad that the national interest as co opted recently is only used to further the interest of those having taken control of those said "national interest" and used for their own benefits.
We need People interest.
