While I enjoyed some of this film, a couple of things bothered me. Judging from the narrator speaking English, the audience of this film was primarily people who speak English. It is inexcusable in 2011 to not have interpretation either with voice over or subtitles of the non-English portions. Glad the people from India, Okinawa, and other non-English speaking people spoke to the cameras. It might have been useful to know what you were talking about.
The other thing that concerned me was the likelihood of the ultra rich to say "we don't need to pay you a living wage. It won't make you any happier anyway." They only briefly mention "once basic needs are met". So I can see this film joining the fake theory of trickle down economics to become part of the "arguments of justification: used by that group to explain to themselves why it's OK to holding on to more and more of the wealth.
