Why do we always get bad news from the media?

No. The world has been in much worse shape in the past than the media portrays. I'm guessing ratings suggest viewers want to hear more negative news, than positive. Also, communication worldwide is instant now. Years ago, news of a car accident in Scotland, wouldn't reach London, or it's media for several days, or weeks. Pictures, video of people being injured, killed, accidents, are more appealing than some kid winning a spelling contest, unfortunately.
