How much stuff that we do is useless these days? To bring up a very pertinent point, Video games are, "Useless". There's plenty of things that we do these days that are purely for enjoyment. And that's not bad, we got things like irrigation and assembly lines, we can afford some fun time.
I actually like the way my College handled this. They had a class called, "Soundings". Basically, they required all freshmen, both semesters, to attend 6 special, "Soundings" events. They consisted of theater, concerts, lectures from guest speakers, even a few comedy events or more esoteric events. Go to 6 of them, get a little culture, learn to like broadening your horizons, you get a credit. Nice way to do it, I think. I ended up going to way more then 6 every year I was there.
Way I see it, there needs to be a few people in art and theater and so on and so forth. How else do you get art, movies, etc? A few of those Majors will become famous and contribute to stuff we enjoy. The rest should see the unlikelihood of success coming, and have a backup plan in a job that just looks for the degree of professionalism you get from just going to college.
