The fairness doctrine was a good thing, but it existed in a different time. Bringing it back today wouldn't address the main issue which is the internet.

When everyone is given a loudspeaker, and the power to create an audience of millions; when "journalism" is equivalent to any random opinion; when anyone with the will and a negligible amount of resources can promote their agenda... No amount of oversight can bring back balanced discussion about actual facts. Reversing a post-truth society cannot happen without radical disruptions to the system that got us here in the first place.
