Some people believe theoretical subjects (mathematics, philosophy, and economy) should not be taught in universities because they should focus on practical subjects (marketing, computing, programming, accounting). To what extent do you agree of disagree?

Universities face pressure to prove economic value, so theoretical subjects are sometimes dismissed as less useful than directly vocational courses. I disagree that mathematics, philosophy, and economics should be removed, because practical competence often depends on abstract reasoning and long-term intellectual foundations.
