Canada is illustrative for another reason. As a country with one of the highest per-capita immigration rates in the world, it is the leading example how multiculturalism can co-exist, if not reinforce, liberal democratic institutions. A big part of Canada’s success relates to what the philosopher Joseph Heath describes as its overarching commitment to efficiency. By efficiency he doesn’t mean the technical efficiency of doing more with less. Rather, he argues with a number of compelling examples that Canadians have internalized the “Pareto improvement” or positive-sum norm as their defining national value. This has allowed Canadians of every race and creed to unite as patriotic Canadians while retaining their more substantive identities as Christian, Sikh, Francophone, Muslim, humanist, and so on. As Heath notes, The official ideology of Canadian multiculturalism was that it promoted a ‘mosaic’ model of immigration, where people can come and keep their cultural practices, in contrast to the supposed ‘melting pot’ model in the US, where everyone is expected to arrive and become an ‘unhyphenated’ American. In actuality, over the last four decades, the two policy paradigms have had the exact opposite effect. The Canadian model, by being extremely accommodating toward cultural difference, was far more successful than the American (or the European) model at integrating new immigrants into mainstream national institutions. Indeed, the thrust of Canada’s multicultural legislation was always pro-integrationist. By generating the presumption of fair treatment in all public institutions (sometimes through exaggerated, bend-over-backwards gestures of accommodation), the multiculturalism policy encouraged immigrants to venture out of their communities – to join political parties, participate in mainstream institutions, and get jobs in places where everyone speaks the language of the majority. In contrast, in America the overarching value, if there is any, is surely something like “liberty and justice for all.” Liberty tends to be more rigid than efficiency, but is nonetheless expansive enough to encompass a large number of sub-identities within it. Khizr Khan, the Muslim American whose son was killed serving in Iraq, demonstrated this at the Democratic National Convention when he held up the U.S. constitution and addressed Donald Trump directly. “Let me ask you,” said Khan, “Have you even read the United States constitution? I will gladly lend you my copy. In this document, look for the words ‘liberty’ and ‘equal protection of law’.” - https://niskanencenter.org/blog/future-liberalism-politicization-everything/
