Network and print conglamorate media are capitlistic enterprises, highly dependent on a mass of consumers who subscribe to them and watch and read ads and buy their advertisors products. Why would you expect them to support a political party and Presidential campaign that has put forth plans that promise to plunge this country into a full blown and certianly prolonged depression, purging the economy of middle class consumers? As you say, even Newscorp knows better than that. And you don't believe anything anybody other than a few elites say anyway, so what skin is off your a**?
