I don't know if you will find a time in US history where the press was accurate, honest, and truthful.
I agree with GP that a primary missing feature is a principled public - without principles people swing wildly in opinion depending on the topic and popular rhetoric.
I see this with much of my own family. They mostly consider themselves conservatives and Republicans of the small government and balanced budget era. Those presumed values go out the window though and when a particular political topic of the day comes up they seem to completely contradict it. The most egregious example in my family is a Ron Paul libertarian that somehow still holds those opinions while supporting virtually everything Trump does.

1) Spare us the US defaultism!
2) If we are going to make this conversation about the USA, didn't US broadcast media have a 'fairness doctrine' that was abolished some years back? Hence the growth in outlets providing heavily biased dishonest news on broadcast media? I suggest this has driven much of the popular rhetoric of which you speak.
Frankly, every country has seen a growth in biased social media "news" sources regardless as to the broadcast media fairness doctrines that still exist in those countries. Deliberate misinformation and a lack of trust in journalism is real.
