Fiction/literature can contribute quite significantly to 'quality of life.' For instance in my n=1 study, it has shown to be one of the most significant factors. If there is one thing about my future of which I am certain, it is that I will always enjoy (and learn from) good fiction.

Basically, people are different; we have different interests. I'm wary of any effort to generalize such a common curriculum.
