Unfortunately, the MSMs deterioration is a side-effect of corporate consolidation, which is a side-effect of monopoly capital and de-regulation.
So the solution is simple, just get rid of capitalism! (jk)
The problem here as with so many things is too-big-ness. For a free press to work, you need multiple voices with multiple viewpoints. When we in the US had smaller, more localized journalism, we got this for free. Reports from California and Alabama and Iowa were automatically going to bring different viewpoints into the discussion. But since it’s now axiomatic that the growth of business must be in no way inhibited by the public (i.e. regulation. Ooo scary!) and that anything a corporation does is protected free speech, we’re very unlikely to be able to realize a solution.
Which might be as simple as breaking up the monopolies in media via regulation limiting the size of companies that can own media outlets. Those outlets could say whatever they wanted (1stA FTW!) but the companies that owned them could not be collected like trading cards by billionaires. The solution to the ills of monoculture is almost always diversity.
