“.... make education only about practical, calculable results .....”
I really don’t know how you can say that! Almost all leftists avoid any mathematics-oriented discipline like it has plague, dengue fever, Ebola & covid! They with all almost no exception emphasis emotionalism over rational thinking! So, they stuff the colleges\universities with unusable content free laughable courses. The former Harvard president but still well-compensated Dr (Ha!) Gay is a prime example!
All that aside, I'm hearing an underlying suggestive voice that literature, humanities, and the liberal arts are useless. That illiteracy is OK and nothing wrong with that.
