This system exists all around the world - Brazil, Switzerland, Finland and other parts of europe, Japan... it doesn’t make a huge difference when the government itself defines
which five issues will be voted on, and I don’t think it could be any different.
Personally, I think the focus should be on education. How can you have vast masses of the world in 2021 electing dumb, retrograde populist leaders? learning history for real, stimulating independent though and intelectual freedom - but that’s way “too leftist” for anyone to take on right now.
And on top of that, accountability for politicians. It should not be a life career, and gross mistakes should mean stepping out so new heads can come in.
