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

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 much simpler and easier to collect and caress the trophies of our democratic inheritance than it is to fashion up-to-date tools with which to work on our current problems.

But that's not how most of the people mentioned in this book became wealthy. Most of them became wealthy by being well connected and crooked. And they are creating a society in which they can commit hugely damaging economic crimes with impunity, and in which only children of the wealthy have the opportunity to become successful.

If allowed to continue, this process will turn the United States into a declining, unfair society with an impoverished, angry, uneducated population under the control of a small, ultrawealthy elite. Such a society would be not only immoral but also eventually unstable, dangerously ripe for religious and political extremism.

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.

When the U.S. government is serious about doing something that's complicated and difficult, it can do it.
