Because Western culture is devoid of any respect for elders as teachers. We have mainstream media to thank for that travesty, and don't get me started on beauty pageants (especially in Latin America.)
In my culture (I'm Eastern Band Cherokee,) elders are the most important members of the nation. There's one gentleman in North Carolina, Walker Calhoun, who is in his 90s and is still performing with the Warriors of Ani-Kituwah, a traditional dance group based on the Qualla Boundary. To us, he's a celebrity in his own right because he's teaching my generation and younger about our traditions. There's no sense of the old ways in modern Western cultures. That's what I like about Leonard Cohen--he knows where he came from and keeps the old ways, but is always willing to try something new and see if it works, while showing the younger people how things are done. That's what it means to truly be an elder, to us anyway.
