I don't know why EU seems to have so much more common sense for issues like these than US, but whatever they are doing is working, and I love it. Maybe US needs to model its democratic system more after EU.
For example, UK elections do not use PR, but elections to the European Parliament in the UK do.
As George Carlin once said: "When you have a selfish, ignorant public, you get selfish, ignorant leaders."
