Maybe some Swiss can clarify why their population is so anti-vax, as it boggles my mind.
My point is not to say that such a direct democratic system wouldn't be effective, I'm just saying that correlation != causation, as in the case of Switzerland, I attribute its success as a country more to it being a neutral banking heaven for the world elite for decades and being in a very fortunate geo-political location that was spared the destruction of war which helped it attract tons of foreign talent and capital, rather than to its direct democratic system and domestic educated population. I could also be wrong of course.
