I am curious why Switzerland isn't more popular among people who want to change the political system. It has direct democracy, decades of success, few problems...
The cynical explanation is that promoting a system someone else invented and tested is not so good for signalling.
Switzerland is pretty small, and it's not obvious to me that its political system would scale well to larger countries. But then again, it's not obvious to me that it wouldn't, either.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
