Scott Spiegelberg, associate professor of music at Depauw University, and author of the blog, Musical Perceptions, suggests that classical music culture could learn a thing or two from folk music culture.
I came to the conclusion that in at least some genres of folk music there was a disdain for polish or virtuosity. Authenticity in these circles was shown by knowing lots of songs in the canon, and through communal performances. Time spent by oneself working on performance craft is less time spent performing with others. I wonder what would happen if classical music took more of that attitude, valuing community over individuality and broader knowledge over specific virtuosity. Jazz has more of that balance, respecting individual skill but also valuing communal improvisation and memorization of the canon.
