The film makes the point (like "I Am" by Tom Shadyac, March 27, 2011) that once we have enough to "live" with relative stability, we really don't "need" more to be happy. There is a happiness difference between $5000 and $100000 a year, but between $100000 and $1 billion (like Facebook's founder). Oh, I recall a meeting of the "People's Party of New Jersey" back in 1972 where they wanted to throw out of the Newark tenement anyone who made more than $5000 a year (me, even then).
The film does indeed make the case for "eusociality" and altruism as intrinsic to humans as social creatures. But we're not Bonobo chimps.
