Europe is god awful at immigration
Its because of their immigration system thats helped the rise of fascism not the amount of immigrants.
Canada this year will be accepting the most immigrants its had since 1957 at around 350k in a country with 35m ppl. Conservative PM Harper actually increased our immigration, gave more power to the provinces, and got rid of the cap on immigrants so that provinces could have as many as they want.
Canada's immigration system is not altruistic however, it comes from P. Trudeau's 1967 point system. We (govt) do not see immigrants as ppl but as economic tools. Europe doesnt have the same opportunity to do so but I figured I'd go over how Canada scouts for immigrants.
What Europe struggles with most of all is multiculturalism. Multiculturalism is the practice of integrating different peoples under one umbrella. It does not mean we Canadians are cultural relativists, it means we seek out immigrants whose views align with our own. Further, part of this practice is settling those immigrants in such a way that they not only integrate but that the majority nation (so white anglophones in Canada) are able to integrate with them as well. Canada's multiculturalism came about because of the anglophone/francophone divide, its about time Europeans other than academics look at how Canada survived the Quiet Revolution (all of our history is the history of this divide however, but the QR is what most ppl will talk about).
