I wonder if the answer lies with government sponsorship of the arts. When the arts are supported, ticket prices can be lower and this might allow families to attend concerts or other performances and introduce their children to the arts from a young age.
Also, in European cultures, there doesn't seem to be such a divide between what is and is not appropriate for children, as there is in the US. Children seem to accompany the parents to whatever the parents are doing, rather than parents choosing to do things specifically geared toward children. Society seem more geared, in general, to adults, rather than kids. |
