The rules that rulers follow: that’s the subject of one of CGP Grey‘s best videos. Three Rules for Rulers comes complete with tips for all types of rulers – dictatorial and democratic.
The advice for rulers in this video are best not taken too literally. After all, money and force aren’t the only motivating factors around. The three rules for rulers are also only one way of looking at a very complicated and nuanced topic. But CGP Grey’s three rules make a pretty good starting point for thinking about what’s necessary.
If you want to delve into the arguments further, here’s the relevant book from the video: The Dictator’s Handbook: Why Bad Behavior is Almost Always Good Politics. As a review pointed out, one weakness of the book and hence the video is its emphasis on rulers as rational and self-interested, with fixed and predictable goals. It’s rather like economics before behavioural economics.
There’s a follow-up video, with more on how rulers rule, which you can watch here.
