For what it's worth, I've made it through the third chapter of the ERE book and I'm impressed with what I'm finding.
I started out my career in engineering, so I'm used to a certain amount of intellectual rigor in the subjects I study. When I shifted over to a business career, however, I found this kind of formal intellectual framework to be lacking, and this lack extends to books in general about building wealth. When I get past the hype, for example, I find books by Robert Allen and Robert Kiyosaki to be useful, but getting past the hype is a major challenge to studying these authors.
I would be surprised if members of the general public would enjoy a nerdy kind of approach to money-related subjects. I would think many people would prefer a how-to or "tell me what to do in X easy-to-follow steps" book to one that delves into the systems theory behind how various aspects of society work. But I also understand the logic against giving people a map with directions because these instructions are useless when the route has changed due to unforeseen circumstances. Teaching people to think and solve problems for themselves is a better way to go (when people are open to learning).
If I had read the ERE book several years ago, I would have rejected it as being too theoretical for what I needed at that time. But now that I'm at a major turning point in my life (thanks to the global debt crisis and all of the changes and opportunities this crisis will create), this student is ready and the teacher has appeared in the form of the ERE book.
