EU has done really well on passing big laws such as GDPR in the recent years, while the US can’t even seem to decide whether to fund their own government. Why do you think Europe is doing better than the US? One would think that since EU is more diverse it would be harder to find common ground. And there were examples of that during the Greece debt crisis. But not anymore, it seems.
There are plenty senates in EU states and EU also has multiple bodies where one state = one vote, and plenty EU resolutions need unanimous vote for passage giving (say 2.1M Slovenia veto over the other half billion people)
Giving more power to the unpopulated rural areas has not gone away at all.
Is that the case for passing things like GDPR?
