    Citizen’s Band radio renders one accessible to a wide variety of people from all walks of life. It should not be forgotten that all walks of life include conceptual artists, dry cleaners, and living poets.
    Fran Lebowitz (b. 1950)

    So while it is true that children are exposed to more information and a greater variety of experiences than were children of the past, it does not follow that they automatically become more sophisticated. We always know much more than we understand, and with the torrent of information to which young people are exposed, the gap between knowing and understanding, between experience and learning, has become even greater than it was in the past.
    David Elkind (20th century)
