"And above all, its immigration policy is tolerant and open-minded, making for the truly multicultural polity that provokes the world’s envy."

Obviously contrast is intended against the immigration policy of the US. The philosophy professor who wrote this article can't quite grasp the difference between legal and illegal immigration. The US has put up with millions of illegal immigrants and is being quite generous and merciful to them. As far as open-mindedness and tolerance goes, I think they've been tops on that.
