I think it should be remembered that universal suffrage is a new thing. It's really only 100 years old at best. In the case of the US, it has only really been universal since the 60s. And Trump is trying to reverse that. Yes, likes of Tynwald is 1k years, but that was not universal till the same 100 years.
And we can see what happens in the system. It ends up with 2 parties, and the policies of each oscillate around a mid point somewhere on the Overton scale. And then boom. It's a 50-50 vote.
But people still want change. Dramatic if possible. We have had changes for the past 100 years that made things better. I DEMAND CHANGE FOR THE BETTER.
But the system can't deliver that. Because it is deadlocked at 50-50. And along comes the far right, same playbook as the Austrian corporal used. And, suddenly we are told that democracy is not really working to make all lives better. Now we are a fractured society.
But we are not really fractured. The main parties are not that far apart. But to win the election, the politicians have to tell us they are far apart.
And then we have other nations with other systems. And as you say, few people actually ask them what their metrics are. We just yell " YOUR SYSTEM IS SHIT, OURS IS BETTER."
And then bomb them. After covertly trying to topple them.
This to me is why the UN is potentially such a strong organization. It has lots of different people at the same table. And along comes Trump saying he will ignore them, do things his way.
But he is doing this without even to trying to understand what a broad Church the UN is. He is the biggest danger to the future of democracy we have had in a long time.
