I disagree, I do think its a good example. Immigration has its pros and cons and smart policies can boost the pros and lessen the cons. Its very clear that immigrants can bring enormous value but its also clear that they can lower the wages of unskilled work, as they have done in the US, and also increase serious crime, as has happened in Sweden and other European countries. The well to do elites that argue taking in immigrants is either always good or a moral imperative, would very quickly change their minds if they were either victimized or out-competed by an immigrant. But since does not happen - problematic immigrants live far away in poor communities and are not able to pursue high paying jobs - they can keep spouting sanctimonious bullshit.
