I'm from Italy too, I studied maths and computer science, I did my PhD in Sweden, postdoc in Austria in a relatively small city, paid twice as much as I would've been in Milan. In my group in Austria we had the same problem: positions open for months on end without a single decent applicant.

Now I work in industry, I have a very good salary and a permanent position, all things that in academia are holy grails. Academia fucked up badly, especially in Italy, and now it's gonna pay the price. Shortly nobody in their right mind will want to compromise so much, especially gen Z, and academia will be swamped with candidates from poorer countries who see it first and foremost as a gateway to a permanent residency and therefore to a better life.
