In my new article, Monopolizing Whiteness, I examine the causes and consequences of “white island districts,” i.e. those that enroll predominantly white and affluent student bodies, despite being in racially and economically diverse metropolitan areas. I theorize that white student segregation in districts like GPSD is a product of (what sociologists refer to as) social closure— a process of subordination whereby an in-group works to curtail an out-group from accessing resources constructed as scarce. I suggest that the "essential facilities" framework of antitrust law can help to illustrate what a legal framework looks like that could appropriately recognize and address the process and harms of social closure.
