This site established by Ray Dalio, the founder of Bridgewater Associates, attempts to educate readers about the nature of domestic and global economies. The flagship media piece on the site is a 30-minute explication of how Dalio understands the economy, using a simple machine metaphor to explain the basic driving forces of the economy, to analyze what leads to ups and downs in the economy, and to define such basic concepts as credit, interest rates, leveraging, and deleveraging. There is also a phalanx of other economics-related resources, including an interview with former US Treasury Secretary Larry Summers. For high school teachers looking to challenge and engage students - or for anyone looking for a quick look into the nature of the forces that shape our fiscal lives, this site has much to offer.
