"The world's first university, The University of Al Qarawiynn, was founded in 895 CE by a woman named Fatima al-Fihri. She used her inheritance to form a large mosque with an associated school"

Even Siddhartha Gautama was a nobleman.
The luxury to spend time thinking and learning has traditionally been afforded to the wealthy, not the working class, and so when young folks now go to uni and feel like it was a scam, it's worth noting this history.
