Speaking as someone who works in a STEM career (lab tech), I think there are many things to learn that are useful knowledge besides STEM. Most of the doctors that I know have an intense interest and involvement with at least one humanity (music, visual art, drama, dance, writing/literature, etc.).
And although I agree that college should prepare students for a career that pays a decent wage, I also think that college is one of the times in a person’s life when they have the opportunity to learn much about people and subjects outside of their career. Once you’re locked into a job/career, it’s hard to find the time to step outside of your comfort zone and meet people who are radically different than you and who challenge everything you believe.
A four-year degree, unless a lot has changed in the last few years, requires a variety of courses from different disciplines. STEM majors are still required to complete electives from the humanities, and Humanities majors are still required to suffer through at least one or two STEM classes.
Both my husband and I attended the same 4-year university, and both of us were science majors/double majors/minors. However, I spent my first year majoring in music–and I don’t regret that. Even when I switched majors, I continued my involvement with the music department, and both my husband and I tried out for and were accepted into the madrigals choir (madrigals were really the cool thing at that time–hard to believe in this day and age, although “acapella” groups are still kinda cool–but not as much as a few years ago). Our madrigal group presented nine evenings of Madrigal Dinners which attracted people from all over the Chicagoland–it was luscious and probably my best memory from college–certainly more memorable than my Biology 200 class, which was taught by an old professor who had a still in his office.
Now I do STEM for a living–and make extra money on the side with music. So it was worth the extra work back in college.
And I never said that students are “obligated to correct their profs.” But as a Christian, I think it’s important to speak up for our faith and recognize that God may have put us there to be a witness to a fellow human being who may not ever meet a Christian again (although he/she probably will). There are plenty of Catholics who have been major influences within academia, thank God.
