This will sound racist but
Europe is better in this respect because Europeans are (or have been until recently) white, homogeneous nations. They are real communities who's ancestors built their countries. So Norway people feel a distant sort of kinship with each other. In the melting pot multicultural America, Canada, Australia it will not work. And soon it will no longer work in multiculturalized new brown Europe. Even if you are 10th generation Pakistani-British or African-French or Arabian-German. Europe is doomed. You dun goofed adopting the immigration policies of America. America is rootless New World. And rootless shall you be too.
Why doesn't Europe take example of the Japan? Hey, they have been on the Nazi side and yet, no one pressures them about their evil racist immigration policies.
