Abundance: The Future Is Better Than You Think by Peter H. Diamandis
Interesting book about how far we have actually come; there are problems, but things are much better than the news make it out to be. It's interesting to see that even though there are defintely problems in the world today, even people with less than ideal living conditions are much better off than comparable people just 20, 50 or 100 years ago. We do have a lot to go to make things better, but we have a really nice base to work from. The whole exponential growth of things like computing power, ability to product things cheaply and so on are helping us here.
