This story just makes me feel sad, and pessimistic for humanity's future. The idea that it was "just okay" for a guy to live in an airport for over 15 years, and lose his freedom of movement and autonomy just because he didn't have papers proving he was born in a particular place... it's just profoundly sad.
It just reminds me of how incredibly petty, violent, and cruel humans are as a whole. We're all people, each deserving life and freedom, and our need to divide ourselves into different, antagonistic tribes is our greatest weakness. And if you can't prove that you're a member of a tribe, you're screwed.
