This isn't a new concept, but the compartmentalization of subjects in school is one of the factors at play along with a hierarchy of subjects and students.

Again, it works to reinforce social statuses rather than dismantle them, often in ways that are detrimental to those actively, albeit unknowingly, contributing to the same systems.
