I believe one of the factors that has caused this is the Insane amounts of money that "talking heads" are paid - Ex: $ Seven million dollars to Jerry Rivers (Geraldo Rivera) ? HUH?! WHY? For What?!
Edward R Murrow or Walter Cronkite Never wore $5K Suits! These people (as most elites ) are Not in touch with the reality of The Common Man.
Another factor is the Buying up of Media outlets by giant corporations that have an agenda with often a Globalist view - social engineering at it's finest. These are the people that tell us "Nationalism is Baaad, Globalism is Good."
