I'd like to address a point made in the original post regarding abundance and economics:
"Another one is about abundance: just believing that there is enough for anyone, is simply not true, as proved not only by economics (which deals with managing scarce resources), but by logic as well..."
While I certainly relate strongly with this viewpoint, I have read a few things that are a bit eye-opening. I would suggest, for anyone seriously interested in researching this aspect of the the law of attraction, to check out two books and authors.
The first is by Paul Zane Pilzer, and economist and an adjunct professor at NYU for 21 years. The book is entitled,
Unlimited Wealth. In a nutshell, Professor Pilzer argues that available resources are a function of technology, and that as technology improves, effective resources increase. An simple example is that as cars become more fuel efficient, the petroleum resources available to us are able to go further than they did in the past. As we become able to do more with less, through technological advancement, our available resources are multiplied. It is beyond the scope of this simple post to elaborate further, but anyone interested might want to look into this resource, as it challenges the underlying assumption of 'limited resources' present in Western economics for the past several hundred years.
A second source of information that addresses the limitations of resources from an economic perspective is provided by Jacque Fresco, and, in particular, his book,
The Best the Money Can't Buy. In summary, Mr. Fresco asserts that using science as a base for building society, there are more than enough resources available today to allow everyone on the planet to have a high standard of living. This is similar, in nature, to Dr. Pilzer's assertion that technology allows us effective access to unlimited resources. Mr. Fresco's assertion is that the monetary system itself produces shortages, not the lack of resources. He sites, as an example, growing up during the depression and seeing empty factories, while unemployed individuals meandered on the streets outside the factory. At the time, there existed enough resources, both labor and material, to operate the factory and produce goods - the only limiting factor was the monetary system - not resources. He advocates a 'resource-based economy', and has many supporters as well as critics.
Both of these views are controversial, but they do present alternative views worth considering, and are supportive of the idea of enough resources being available to support everyone's desires - a fundamental tenet of the Law of Attraction.
