Public school is at at least 2 levels if not more. Elite will remain in their own world. Rich will just pour money on their kids education, middle class and the poor are fucked.
In France, most 18 years old would fail the brevet (end of middle school degree) as it was given in 1950s/60s. All the exams are pure jokes, and we see it in international education survey (PISA or even better TIMMS, level are dropping beside for the top 5%)

I want self-taught to be viable. I consider myself self-taught. I am one of those liberal arts majors that made my way into a data engineering career. I don't regret taking liberal arts but that's more due to a combination of luck, privilege, and personality.

I personally read "The Scapegoat" but Girard is doing literary critique which, like philosophy, can be dense and difficult to read if one isn't used to such texts. Personally, I would like to read "Deceit, Desire and the Novel: Self and Other in Literary Structure" sometime in the future.
Girard was a literary scholar who focused on myths and mimetic desire was just one part of his analysis of mythical or narrative texts. The other large part of his analysis is related to the scapegoat and how it is the "mortar" for building communal and religious social structures. Certainly read some of his essay collections or even one of his longer books. At the very least read a summary online.
