@holeinthehead2 There's the GOP's virulent anti-intellectualism, going back at least to Ronnie Raygun and his CIA handler Papa-Bush. Then there's the end of the fairness doctrine, which opened the door for polititainment. Then there's the "profitable platforming" effect: Man on the street interviews are cheaper than real reporting and just as good or better for ratings...thus for ad sales.
And, yeah, even Lao Tzu says to keep the plebes fat dumb and happy.
