For those who see value in reproducing the systems of domination in which they are positioned at the top, university education should only function to perpetuate their dominance. Naturally subjects which offer the ability to challenge this are discouraged and ridiculued.
They scream "STEM only" because they're aware that subjects that are powerfully designed to cause one to think critically & creatively (Arts & Humanities; social sciences) is a HUGE threat to oppressive powers. Don't be fooled to think they truly believe these degrees are useless
