From the article, this is so incisive:

The problem I have with a lot of investigative journalism, is that they always say: “There should be more investigative journalism” and I think, “When you tell me that a lot of rich people aren't paying tax, I’m shocked but I’m not surprised because I know that. I don’t want to read another article that tells me that”. What I want is an article that tells me why, when I’m told that, nothing happens and nothing changes. And no one has ever explained that to me.
