"... how much happier we would all be if we gave up following the news and devoted ourselves to more edifying pursuits."
Then why don't we all do just that. If enough of us boycotted newspapers and news magazines and news shows, the drop in circulation and ratings and revenue might actually get the attention not only of the media moguls, but also of the people most often featured in the news, namely, craven politicians and fatuous stars and celebrities. It would be wonderful for them to realize how much we could do without them. In the meantime the rest of us could engage in what C.S. Lewis called a "lived dialectic" with great art, music and literature - and, by extension, with life itself.
