Working at a big box music store for many years, I used to hear similar rants now and then. Maybe not so angry, but parents would sometimes say to me something like "I don't understand what he wants to get into this for, seems like a waste of time to me"
I wish I had had DeepDrummers quote - "The importance of music is lost on those who can't hear it."
My mom's 77 and still makes it out to most of my gigs. I'll thank her at tomorrow nights.
