I think it comes from really liking literary forms. Poetry is very beautiful but the space on the page can be as affecting as where the text is. Like when Miles Davis doesn't play it has a poignancy to it.
We can't go to people who have lost their job at GM and say 'Oh by the way we are going to pay money to build a road here or inoculate children there ' unless we can demonstrate that it is in America's interest. I happen to think it is.
