A very high fraction of America's economic problems come not from our difficulties with education or globalization or competition with the Chinese or whatever. But they come from the fact that a small number of wealthy and powerful people who run dangerous and/or inefficient companies are able, through the use of money in the political process, to prevent the government from regulating them properly.

It is no exaggeration to say that since the 1980s, much of the global financial sector has become criminalised, creating an industry culture that tolerates or even encourages systematic fraud. The behaviour that caused the mortgage bubble and financial crisis of 2008 was a natural outcome and continuation of this pattern, rather than some kind of economic accident.

A fierce and sentimental addiction to forms makes us shudder at change. It is much easier to say that the system is all right-only the people need to be improved.

When the financial crisis arrived, it seemed to me that this was something I had to make a movie about.

I thought I should try something relatively inexpensive, relatively contained, relatively small. I started working on a feature, a film I'd still like to make: a very talky film of people and ideas about our contemporary state with regard to relationships, marriage, sex, and romance. I started trying to educate myself about filmmaking.

WikiLeaks combines several of my prior interests in technology, policy questions, and journalism.

The real challenge is figuring out how the United States can regain control of its future from its new oligarchy and restore its position as a prosperous, fair, well-educated nation. For if we don't, the current pattern of great concentration of wealth and power will worsen, and we may face the steady immiseration of most of the American population.
