My apologies for the commercialish lack of answers here, but I thought this was interesting from the perspective of explaining our monetary system and future of oil and energy. Chris Martenson has a book out called The Crash Course that explains how the next 20 years will look like nothing we've seen before. The first 10 to 15 minutes are real good. His talk ends before the question and answer period and unfortunately he doesn't provide how we fix this. I guess that's why you have to buy the book.
(Think exponential growth of population, oil demand, debt based money, etc.)
