I don't think that people don't want to think about the world's problems. We get that 24/7 it seems. Rather, people need a way to relax and have normally gotten that through books, TV, movies, and games.

Now all of those formats (ESPECIALLY books) have always had ones that were QUITE political, but there was also a lot of content that was just for relaxing and escaping from the reality of the world which has always sucked. Recently, it seems like they've started really ramping up the political content in many movies, shows, and games and some people certainly enjoy that, but then again...a lot of people don't like being preached to in every aspect of their lives.
