I wasn't particularly excited to learn philosophy or economics, but that gave me the foundation to understand Marx and Engels. Learning "things you're not necessarily excited about" makes you well-rounded. That's a _good thing_.
Let's use another example. Communicating with other people is a very important part of my job as a software engineer. I'd say that at this point in my career, writing good proposals, documentation, project charters, task orders, change requests, etc. is vital to my individual and collective success, so I'm glad I was taught lots of rhetoric and literature and writing and all that artsy stuff my younger self spent too much time disdaining.
Or another example. I have written precisely zero lines of Lisp or ML for work, and I flunked the first computer science class I took that used Lisp (good old _Essentials of Programming Languages_). And yet I use the concepts I learned in those classes _all the time_. Heck, I was just talking about side effects the other day in the context of 21 CFR Part 11 computer system validation.
My last metaphor. Brushing one's teeth or taking a shower isn't particularly exciting, but that kind of routine maintenance work is a vital part of your physical health. So it goes for mental exercise. Reading something challenging, learning the work's historical context, and writing a critical response well all helps keep you mentally healthy. That's good no matter what socioeconomic system you live in.
