some of the most interesting economic observations concern relative abundance. Look at our standard of living compared to 100 years ago. Look at South Korea compared with North Korea. Robert Lucas famously said that "The consequences for human welfare involved in questions like these are simply staggering: Once one starts to think about them it is hard to think of anything else."
The standard economics textbook does not treat the issues of "relative abundance" very well. I think that there is a market opportunity for a book that can fix that.
I'm pretty sure such a book was written; it even sold a few million copies. Indeed, I've long thought Arnold Kling would benefit from reading it...
