Half of our species (chosen randomly with the flip of a coin at birth) are locked away forever, generating energy, goods, and food for us, while consuming the bare minimum, unclothed. They do so in dark skyscrapers without windows, lest they learn what's out there. But one might say they're the lucky ones. After all, we’re out here struggling—competing for bigger houses, better promotions, more attractive partners, trying to improve our art or learn more languages—and thus always cognizant of the world’s immense inequalities. How fortunate the other half is—to never know what they're missing, locked in the dark, toiling.
