Even "hard" topics like chemistry and medicine give very limited opportunities to Italian graduates today (since the chemical industry has basically disappeared, and there is an overabundance of medical personnel in a context of shrinking public funds). More industry-oriented ones like CS and EE do provide jobs but not necessarily
careers like they used to, since the entire workforce is now expected to have a degree.
I'm not saying degrees are "devalued" (European opportunities abound, after all, and most Italian graduates are actually very smart), but it illustrates that making education (almost) free will always result in growing numbers of graduates from all backgrounds. This is a good thing overall IMHO, but should be expected and planned for.
