Some people just want to spend their time learning about Gothic art or about Persian poetry instead of fixing other people's plumbing, there's nothing wrong with that, quite the contrary.
And to add a further non-apocryphal anecdote: I'm probably never going to be reach (I'm approaching 40 and you kind of feel this sort of things) but were I to die tomorrow one of my best memories/things that happened in my life would be the fact that I got to appreciate the poetry of Hafez [1] because of my dad. He had a book of his in our library, I knew my dad liked his poetry so one day I just picked the book and I liked his poetry, too. It became a sort of a new bond between me and my dad that I can still feel now, 20+ years after I had first read Hafez's poems.
More to the point, not everything in life is about money.
