Wealth inequality has produced various spaces of security throughout history. Today, as inequality within nation-states returns to early 20th-century levels, security capitalism is raising walls, dividing cities and littering the world with surveillance gadgetry—thus reinforcing social divisions both spatially and symbolically. Scholars and activists typically tie securitization to fear of crime, social upheaval and other insecurities. People often accept securitization, perhaps even naturalize it, as a response to real or imagined fears rather than examining its cultural embeddedness. But if the link between securitization and fear of crime is broken or weak, what motivates people’s desire for security? Here, we add to previous anthropological work on spaces of security by attending to the ideas, embodied behaviors, desires and privileges that shape what we are calling “interiority.”
