This is also definitely true.
My step dad loves art. He studied it and he loves it.
I 100% readily admit that I have no formal art training to help me understand why something along the lines of an empty tin can or a seemingly incoherent splash of paint has intrinsic value.
Saying that, there's only so much time in the day and space in one's brain so I suppose there's also an argument to say people simply have other things to be getting on with.
Yeah, and this is why art education is so bad. Ultimately people think of it as something very low on the totem pole of priorities and they would rather focus on applicable and productive subjects, so it receives very little attention.
