Why?

Why does the mainstream media shill for the Left?

1.  The owners of the mainstream media will only retain and promote Leftists journalists and commentators.
2. The reporters are Leftists,and bringing down America and Western Civilization is their dearest objective.
3. The reporter can only survive in that culture by mouthing the party line, and not deviating from the tropes and memes to be fed to the masses to be consistent with their favorite narratives.
4. Reporters are cunning. They know that the masses are swayed by what reporters as authority figures write and speak of. They report the news that advances their agenda, and suppress and exclude news that runs against the reality they seek to spin.
5. They know the masses don't think for themselves, do not question what authorities tell them, are bred to be enslaved, to be submissive, to be told what to think and how to act, and whom to accept and whom to reject.
6. Reporters realize that brainwashing the masses is to steer them to serve as a majority of Americans in reform of Progressive reforms and social justice.
7. Reporters like being part of the political class that controls what the masses think and do as all are made wards of the State as the Leviathan grows ever bigger and more intrusive in peoples' lives.
