That is an easy assumption, and one which had me flummoxed for many years. The truth is that journalists are just like you, feckless and arrogant. They think nothing of sawing on the limb they are standing on, not even thinking of the consequence if they actually succeeded. They, like you, want a utopia. But not a real, existing one of course--Utopia means "nowhere," and no existing dictatorship will ever suit as well as the "horrible" US.
Free, competitive journalism is anticonservative in nature--always has been, always will be.
The truth is that journalists are not in control. to suggest that is offensive. do we suggest that workers on the line decides what kinds of cars, and in what kinds of colors, GM will make?
Trust me. if journalists p-off their bosses, they get fired. just like everyone else who has a boss. It doesn't happen so often because the ones likely to do something like that don't make it very far in the business -- they self-select or get out early enough to not make a splash. methinks you've bought the myth of the "liberal media".
