A lot of these things change slowly (and are decades in the making), but aren't apparent until they have changed too much to easily fix so they require a lot of collective work to restore, which is extremely difficult because it often works against the incentives laid out by the environment that caused them to be this way. Using the news example, media sources could simply try to become more rigorous in their pursuit of being trustworthy again, but clearly society has incentivized them to move in the way they have. Running against those incentives runs the risk that it just makes them unprofitable again and then unable to report news all together when they go out of business (or become bought out by wealthy interests with an agenda). So the 'solution' would have to come in some sort of innovation in how people consume media that aligns journalistic rigor and being profitable, which nobody has really figured out how to do yet.
