The general decline in social infrastructure is yet another contributing factor that Petersen cites in discussing the lack of social cohesion found in millennials and Gen Z. Such an infrastructure, she writes, consisting of spaces “public and private, from libraries to supper clubs and synagogues . . . made it easy to cultivate informal, nonmonetary ties. These places still exist, but they have become less central, and less vital, and, most importantly, less accessible.”
