Explaining the problems of capitalism in a nutshell, it's Michael Moore, known for many controversial works such as Bowling for Columbine, and Fahrenheit 9/11. This film did not make as much of a splash as those though, probably in part because money isn't as interesting as tragedy, and partly because most people will agree with what this film espouses (at least, to some degree).
The film was made in the wake of the financial crisis in 2008, which resulted in the bailout of Americas biggest banks by the government. While I think it is by no means his 'Magnum Opus' (see the quote on the cover), it's interesting that this film seems to come full circle - he starts the film in his home city of Flint, Michigan, which was the subject of his first ever film, Roger & Me. Moore observes that the desperation and social decay that occurred there when the GM factory closed down years ago, is being repeated all over America with the growing power of the banks.
