That's a paradoxical statement in a sense. See we are primates. We arent as advanced as many think. Behavioral patterns of humans directly mimic those of our primate cousins. Outside of complex, conscious thought which is quite mystical and mythical these days most of our actions are in the end a factor of our survival instincts. By having a $20,000,000,000 value placed on your name, yourl are guaranteed shelter, protection, food and well you could be rumplestiltskin and still be guaranteed offspring by the most attractive of women. Haf wanting to guard the border is just like the chimps that patrol the edges of their territory and the howlers that well... they howl!
