The press in the US is obviously not free, as practically everyone else in this thread already mentioned, and I believe mostly for the reasons previously stated: they are paid by people that have a vested interest in spreading their views. Now, there are exception to this, usually in the form of small, mostly online based companies, that don't receive state or corporate funding and rely on public donations instead. Examples are Democracy Now (
http://www.democracynow.org/), The Young Turks (
http://www.youtube.com/user/TheYoungTurks/featured), The Real News Network (
http://therealnews.com/t2/), and so on.
However, I think a more interesting topic would be in what way a "good education" may influence this by limiting the spectrum of "acceptable" opinions. You see, in most cases, I don't believe there actually is anyone telling journalists and editors they can't report on something, or that they need to do so through a specific view; people are groomed to accept it. Then those that more easily rise through the ranks are those that have internalized those views.
As a practical "try it yourself at home" example, what if someone told you that every American president since the second world war ought to be brought before an international court and tried for war crimes?
