I'm just going quote the original article here: "Of those who do choose to move to New Zealand permanently, analysis of the New Zealand General Social Survey show immigrants integrate well. They are less likely to claim a benefit, more likely to be employed, and their children have better education outcomes than native born New Zealanders."

This is rich. Singapore's official languages are Malay, Mandarin, Tamil, and English. The official national language is Malay. Let me take a wild guess ... as an immigrant to Singapore, you've been studiously learning Malay, Mandarin and Tamil, and you absolutely do not segregate into a clique of white anglophones in your social life. Good for you, model immigrant that you are. /s
