You can make the same argument about American news media. Fox News and MSNBC are propaganda machines for their respective political views/parties. I’m not sure what your comment adds to the discussion.
That is, I'm sure there will be no shortage of people who will explain how Fox News and MSNBC are happy to talk about problems as long as they don't rock the boat. It's fine to continuously speak about crumbling infrastructure, but it's not as fine to speak about the economical benefits of war and that the society happily accepts the death of hundreds of thousands of foreigners for it, because that would become very uncomfortable very quickly.
I'm not sure what you mean with the last parts of your sentence. I've definitely seen stories from Fox News and MSNBC about the economical benefits of war or foreigners dying in war. Many of the anchors on those networks take great pride in making things uncomfortable for the powers that be, although they disagree on precisely who those powerful people are.
