I think Ray Dalio does a good job talking about the decline of the American empire, but I'm not sure his huge bets on the rise of China are well-placed. India also appears to have a good case for "next big empire" and it is often the case that when two world powers fight, they destroy each other. For example, the UK and Germany in WWII - the UK won the war, but ended up in huge financial trouble that caused its decline.
