The Zeitgeist economics are odd, they try to imply that they can completely eliminate subjective value, which is clearly a nonsense. As stated further up, the analysis stages earlier on in the series are better than the economic solutions, but even there, it's mostly a patchwork of other people's research.

If I can credit the series with any longevity value, it's that watching it "woke me up" (in a way that catching Alex Jones never would have). I found myself, like many others, not 100% accepting what Zeitgeist says, but it catalysed me into researching the issues myself. And I ended up picking up bitcoin along the way, so it did it's "wake up" job pretty well. Still agree with many parts; the John Perkins section, 9/11, emergent nature of reality/knowledge, origins of religion (although I'd already heard that stuff before zeitgeist anyway, and there's a whole lot more to it that's a pretty important part of that picture, Zeitgeist lazily stuck to the Jordan Maxwell view exclusively).

But communism (or whatever you choose to call it) is not the answer. It would be, if we had infinite resources (or as good as infinite). There really would be no need for money under those circumstances.
