Doing it right takes years of practice, and not everybody is going to enjoy it well enough to get through the nonsense needed to make it worthwhile.
Imagine if every child in our fine state was required to play harmonica competently, no matter what their interests.
We could devise a state test where most kids would pass, and we could pat ourselves on the back for demonstrating that our children play as well as their Chinese counterparts.
But I wouldn't want to sit through a recital....
Time spent studying something that gives no joy is just spent time.
