Something that may be of interest - the below article covers Ray Dalio, the leader of one of the largest hedge funds in the world, Bridgewater Associates. The article is on the long side and covers a lot about the guy and the corporate culture at his company. But he basically has been (and continues to be) betting on economic collapse in the next year or two.
This is a paper he wrote (mentioned in the article). About 20 pages, but gives a good overview on various aspects of how the economic system works.
