Why can't there be a human kind that doesn't "lie all day every day"?
(1) "lie" has intent. You can't prove intent on the scale you accuse.
(2) "The media" is amorphous. Ask any two people and they won't identify the exact same group. Ironically, this is the same problem with the concept of "race", "species", and a few other similar concepts of population.
(3) The suffix "establishment" in this context is ridiculously vague to the point of being a No True Scotsman fallacy.
IMHO people complaining about "the mainstream media" have no historical anchor. Things were an order of magnitude worse when Hearst was actively running his "yellow journalism" outlets and when governments had monopolies on media coverage.
Media literacy is hard now because there is more than one choice for news. I choose not to get my news from the impulse isle or from {TMZ, E! Television, Fox News, MSNBC, local television affiliates}. There are still thousands if not millions of media outlets that don't "lie all day every day", the only difference is now there is more onus on the reader to be able to distinguish journalism from opinion from sponsored stories from entertainment from outright fraudulent stories.
