Why do you act like it's a given that it's in a British citizen's interest to increase immigration? This goes for British citizens of South Asian descent. What have they got to gain?

I'm always surprised to see people with this "we need endless immigration or you won't have diverse restaurants" mentality. And it's always coming from the most privileged people in society, and always condescendingly talking down to people who don't vote like they do. (i.e. people like Guardian writers and you)
