For the idea that "Inside Every Utopia is a Dystopia," the 1973 story "The Ones Who Walk Away from Omelas" by Ursula K. Le Guin [2] has always most starkly impressed this concept into my mind. In it, Omelas is a perfect utopian city where life is perfect, except this perfection is dependent on the incredible suffering of a single child kept hidden away in a dark place. At a certain age, child's suffering is revealed to each citizen. Most residents learn to live with this fact or rationalize it away. It's a serious oversimplification of certain dimensions of our own modern societies, but it is a powerful metaphor for thinking about how much our cheap modern conveniences rely on the services of minorities and the impoverished who serve us and manufacture our many shiny things. I wish this essay had delved deeper into this concept.
