For those of you familiar with Zeitgeist, an addendum has been released I found this earlier today, don't know if anyone else has seen it yet.
Although it is less an addendum than a whole other 2 hour movie.
This one focuses on the flaws of the banking system we live in, and reveals some startling truths that I personally have been fumbling for ways to put my finger on it. This video did it for me in many ways.
It goes beyond this, however, as it reexamines society as a whole and looks to see what can be done and what we as human beings can do for the future.
I think it's worth noting that someone who grew up Christian and presently describes themselves as a Spiritual Mystic (when I'm forced to put a name on my beliefs) agrees with this video's worldview for the future (the person who came up with all this calls himself an atheist). It is the next phase of evolution that must occur in our world in order to survive.
It also offers practical solutions to how to bring change about. Something I will be beginning to work on tomorrow (specifically step one).
