Except that, by any objective measure, the news is NOT negative. The world is most peaceful.
No. You are confusing what is happening, the facts with the news. At the moment, the news may very well be the worst of all times, even if the facts aren't.
If you think that the reality of what is happening in the world is mostly negative, you should reconsider your news sources, and get a more balanced perspective.
The OP's personal source of news is irrelevant in this discussion. Bad news sells better than good news, even for the NYT and the WSJ. As TFA puts it "...they have an incentive to pursue alarmist stories that generate clicks."
