> [...] foreigners make up about 30% of the resident population - a much higher portion than the USA, for example!
I mostly disagree with acyou's comment, but since Singapore is a city as much as a state, the more enlightening comparison might be with how many of eg New York City's residents were born out of town? (Or perhaps how many of NYC's residents were born out of the country? It's murky, and there might not be one best comparison.)
In any case, I agree that Singapore is not 'monocultural'.
To push your point a bit further, my high school History teacher (I went to HS in NYC), would constantly remind us that New York was nothing like the rest of America.
