There is the common misconception in modern society that the news media is concerned with telling you the truth. I am sure there are some journalists out there who uphold some standards of truth telling, however the vast majority know their place is in the entertainment business.
Its not about telling the truth, its about telling people a fractured version of factual events. The version that entices them to watch more, and not be so confronting as to turn the channel.
And i can see that you can view the world as either filled with misery, or filled with love, and each would have certain validity in the viewpoint expressed. But what we are shown and told on a daily basis from the media is that there is bad shit that happens, things will always be this way and there is not a thing that we can do about it.
We really need to get away from the concept of news, and start to develop programs more around action. Like instead of seeing a passive showreel of atrocities on different scales, we should see programming showing people who are getting a foothold against the machine of endless growth, greed and capitalism and are starting to put people, and the world in front of bottom lines and balance sheets.
