There are so many things that so many people say should be "required learning in school". I sympathise the sentiment, but maybe it'd be better to habituate ourselves to somehow thinking about how each of us could solve the problem (for kids) instead of trying to elbow in our favourite subject in an already stuffed-to-the-brim curriculum. Just a thought.
Against my better judgement, I'll go ahead and bite.
There are two things in your comment I want to address. First, I'm not sure what you mean by "the problem," so I'll assume you mean the question of what constitutes a solid education. Second, there's an underlying debate here of another question, what is the purpose of education?
I'd argue the second question begets the first, for how can you determine what constitutes education until you know what the purpose of it is? For example, is the purpose to be trained for a job, or to be able to think critically and ask fundamental questions about the nature of life?
If the answer is the former, then I would agree with you that no lesson should be allowed unless it can be directly followed along to a relevant skill at a job. But I think the answer ought to be the latter, and in that case, the questions posted by Campbell's responses in "Power of Myth" and exploration of ideas and narratives that many of us simply take for granted, compel one to have serious reflection; even better that the pivot is Star Wars, a story with which many people are already well acquainted.
So, while I was using a rather casual colloquialism, hopefully this reasoning justifies its use :)
