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.

Any attempt to disturb the deadly routine of instruction is looked upon as sabotage. And the notion that the aims and functions of education should be determined in the local community by a close and continuous discussion among students, faculty, administration, and citizens is so visionary that it is not even seriously considered.

Forgive me, I must start by pointing out that three years after our horrific financial crisis caused by financial fraud, not a single financial executive has gone to jail, and that's wrong.

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.

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.

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