The problem is that the previous consensus was created by corporate centralized media, and in many ways was actually against the interests of most people who accepted it. Now that corporate consensus has fallen apart, so we've got two tribes each focused on the specific ways they were screwed over, with each ascribing the previous state of affairs to the other tribe. In a vacuum their differences could certainly be worked out to support a consensus. But given how well ragebait sensationalism seems to work, and the popularity of feel-good (well, feel-something at least) authoritarian demagogues like Trump, I don't see much hope.
