Yeah, that is a democratic problem of federal entities. In the EU it is the veto power that gives smaller states a way to throw a wrench into any developments. It is not good there either. one of the big reasons why the EU is failing in so many ways is that it is unable to make decisions.

The US doesn't have this problem but instead, they have these neverending stories of small rural states being overrepresented in the presidential elections. And I am sure you are right that they will never give up that advantage.
