It's a shame that calculus isn't required by every college degree. Just because I'm not integrating functions during my normal work, doesn't mean I don't benefit from understanding the fundamental principles.
Yes, totally. I was about to undero surgery but found out the doctor didn't even know about Laplace transforms. He small-mindedly spent his formative years learning anatomy, never benefitting from the knowledge of frequency-domain derivatives. I dodged that bullet by storming out.
Would you say the same about learning Christianity: maybe not directly useful for your job, however it is rather foundational to much of English society.
