Suggested

When a privileged legal status is universalized primarily for fiscal and administrative convenience, it loses its capacity to grant meaningful privilege—shifting the mechanism of state power from selective inclusion to universal extraction, while forcing society to erect new, informal hierarchies (such as the honestiores/humiliores divide) to maintain class stratification.

• Article: An article analyzing how the exclusion of edge-case legal categories (Junian Latins, dediticii, and conquered barbarians) post-212 CE reveals that imperial universalism relies on maintaining functional ‘underclass’ populations for cheap labor and flexible subjugation.
