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.
Radical conservatives who are not interested in a compromise gained a lot of power in the USA. Because as long as enough people are interested in finding a compromise, you can always find one.
