I got into trouble a while ago for saying that I thought the internet led to increased literacy - people scolded me about the shocking grammar to be found online - but I was talking about fundamentals: quite simply, you can't use the net unless you can read.

The only way you can write the truth is to assume that what you set down will never be read. Not by any other person, and not even by yourself at some later date. Otherwise you begin excusing yourself. You must see the writing as emerging like a long scroll of ink from the index finger of your right hand; you must see your left hand erasing it.

It was exciting to work with director Jennifer Baichwal, who made Manufactured Landscapes and others, on the film of Payback: Debt and the Shadow Side of Wealth. It's called, simply, PAYBACK. Jennifer didn't want to do a transliteration of the book, a kind of illustrated version, but to go into the core of the book: owing and being owed, paying and paying back, on all sorts of levels. So she found real-life, visceral stories that embodied the themes of the book.
