Whatever Happened to the Political Novel?

Is the socially conscious novel a dead genre? Whatever happened to the idea that a book can change the world? Are authors so intent on their own characters that they can’t be bothered to make their plots politically relevant to our increasingly dangerous world? Ray Conlogue is only asking, but modern authors seem increasingly hostile to the notion that they could actually advance political ideas or social agendas with their works of fiction. These days, novelists are perfectly within their rights to spend hours working on behalf of whatever causes they support, but to put the crusade to paper would apparently cross some invisible line of decorum.
