I think we have a strong disagreement here, at least in India the income Level 3 is decent enough to be able to buy and read this book. What I mean is using the same currency for all over the world, even though a range of value probably isn't a convincing way to categorize. I believe that if we do it by considering the average living expenses in particuar countries, it would make more sense than it does now.
