It's complicated ... and that's the point. Journalism doesn't have all the answers, and we shouldn't expect it to. We shouldn't expect our stories to solve things for us.
Journalists' primary role is not to answer the challenges that face our society: it's to bring light to those challenges, so that those with the proper tools to solve a given problem will know that the challenge exists. In a sense, we're brokers, we're middle-men, we're matchmakers between problems and solutions. But those problems and solutions still have to get to know one another, find the right match. We can't consummate their relationships, we can just help them find one another.
