In this case, the article mentions "meatier yields", and that two-word combination by itself is something I would bet on in a fight against any article-length analysis of the 2008 crisis.
The haves will gain and use knowledge and technology to make their lives and those of their tribe easier and it will benefit them more than those of the have-nots.
So written language containing the body of science and technical knowledge benefits them always. The effect on the entire species is unimportant to those with comfortable, limited lives.
Other non-technical written language to create a world of mystical morality to keep the other side in check also benefits the haves.
Until the human species changes into something new where competitive behavior is not a base need/instinct, nothing will ever change.
You can't escape this.
