The answer as to why most Americans are blind to the reality is that for all intents and purposes the media that claims to speak for us instead speaks for the oligarchy generally. While sometimes a reporter will manage to say what needs to be said so as to inform people of the details about their reality, mostly that is only one reporter out of many and that person only being heard by some people not all. Moreover if you contrast a biased reporting outlet like Fux News, you have a significant percentage of the population being purposefully misled as well.
It is the media’s failure to be independent of the oligarchy’s self interest that trips us all up constantly! Inevitably, no matter what the issue, there is never any consensus that the public can come together on. The coming climate catastrophe is starting to be understood by everyone but that is recent at best. Five years ago the media was still never saying the words climate change or that the mega weather events and things like our snowless winters that have kept on happening has finally persuaded the public that these events were caused by climate change but the media lagged behind. It really screws us that they do. Bernie has opened the door for many progressive issues but it will only become reality if people write letters to the editor and force our media to actually speak for the public as advocates. At present most of our media speaks for the oligarchy.
The media which is supposed to speak for us and teach us, does neither. We need to bring democracy … into our media! They have to represent us - the public… but I think most have forgotten how.
