Amen!
As for learning about arts and literature, you can go to libraries or museums. For a few thousand you can spend money on a bus ticket, hotel, enjoy a nice trip to the various museums or other places or save and buy books on the subject and read them.
Not spend time wasting money on lectures. If you are too lazy to learn about art in your own time, you’re obviously unmotivated to make something of that degree you’ll be buying.
Amen to that.
College, IMO, should be for teaching you things that are difficult to learn on your own. I don’t want my brain surgeon to learn via how-to books. Similarly for the person who designs the bridges I drive over.
OTOH, I see no need for actors to have any sort of degree. And if you want some appreciation for the arts, 99% of it can be acquired, as you say, through libraries and museums. The only exception I might make is that I suspect some music education could be relevant. But I think that is better taught at a conservatory than a university. (I’m willing to hear other arguments by those more knowledgeable.)
I have a heavy duty tech education, with virtually no liberal arts. Yet I know more about the arts than most people with an arts degree. I’d be willing to take on most of our liberal arts educated congress critters in a liberal arts competition. I bet I could beat 0vomit, the “constitutional scholar” in a test on the Constitution. (And history is one of my weakest subject, having never taken a history class after completing the mandatory minimum in high school.)
