I also meant in terms of effect. Yes, you will find things exposed in various media outlets. But if I turn on CNN during a Republican presidency I see people on the edge of rage-quitting life and if I turn on Fox News during a Democratic presidency I see McCarthyism is alive and well. And if I do the opposite I see literal propaganda. I don't think most of their viewers are really looking for truth but are basking in deep, echo-ey pools (or sensory deprivation chambers, if you please) of confirmation bias.
There are far better news outlets, and I agree that press and media need to exist and be free for the purpose proposed above, I would just argue that in the most popular media, that isn't really what's happening for most of their audience, and I personally am far happier not seeking out mainstream news myself because of how sensationalist and biased most of it is. I'll eat my hotel breakfasts and airport snacks somewhere other than in front of the complimentary TV.
