Hmm. Thanks for the replies, people! Personal finances aside, though, I was hoping for something a little more mathy. The psychology of making or keeping your money... well, it's great these people found a way to turn a buck selling that sort of thing to hopeful Americans, but after reading a few pages of RDPD, I definitely wouldn't buy it.
Does anyone have a suggestion that would get a little more into the actual mechanics of debt - explaining compound interest, different types of loans and how they work, etc.? Or do I have to ask bankers themselves? I don't know where to begin, even with the rudiments like "How to take out a loan", "Where to look for a loan", "What to look for in a loan", "How to figure out which loan is better", etc...
