I note that at http://users.ox.ac.uk/~worc0337/why_phil.html there is a set of for/against arguments dealing with this topic – and links to the many University Departments who offer a rationale for such studies.
At Elon University, Nim Batchelor has a page entitled: How can I tell my parents that I want to be a philosophy major?
But – what do those who are actively studying on a philosophy course – or active in philosophy as teachers or in some other sense – think?
Does the study of philosophy make you:
More content – or more despairing and miserable?
A better (more virtuous) person?
Awkward and disputatious?
Smug and self-righteous?
Or perhaps the study of it has benefits that aren’t as clear and as much to do with what impact it has on the individual student…
