If you watch the film, you'll no doubt notice half of the interviews talked about "abundance" or basically making money with LOA. One guy was moved to tears because the picture of a big house he had on his vision board turned out to be the one he found himself living in some time later. Now this is really simple: If the Law of Attraction is a spiritual principle, which I would not dispute, then what does it say when you use that for things that relate to egoic desires? The thing is, I've never heard of anyone use it to feed their family when they are starving, OR more significantly, use it for anyone other than themselves.
This really speaks to the subject of evil because when you put this basic attractive principle with greed and this insatiable desire to consume, it doesn't take a genius to see that it's unsustainable. It really underlines a way that evil works in the world, because when your world view is all about me and you have to take from someone else, it is indeed very much like a Ponzi scheme, where you have to recruit new blood to feed the ones that were exploited before - it's a pyramid. Contrast this with love, where cooperation and mutual support is involved, it really shows what the typical idea of "success" in the world entails.
