Journalism as a whole has been eroded on many fronts, but prominently by business. You're right that this article doesn't mention that particular tactic, but for people who are unaware, I think that the information in the article is a good starting point.
Totally. This article is brief, and they obviously can't touch on everything. I just think that the info I referenced above should be common knowledge, and for some reason it's barely even heard about. It's extortion by these companies, because it usually goes like this: "Man, we really love operating in America, but it's just too darn expensive. I guess we're gonna have to move to Mexico. Sigh...If only there was a way to make our tax burden lighter. Oh wait, what's that you say Mr. Congressman? You'd be will to give my poor little multinational, multibillion dollar corporation a $50,000,000 annual break?! Gee whiz that's awful nice of you. Aww shucks, I'm blushing."
Heh, you forgot the "thanks [dad, family friend, co-owner of a subsidiary, etc.]". I really wonder what the world looks like from the top of a mountain of cash . . . But yes, you are right. There's a lot of effort that goes into keeping things from being common knowledge and no real counterbalance that makes things as easily accessible for people. That would be a hell of an undertaking though.
