The situation in Singapore is different. The foreigners are not high-income people who chose to live there. Only about 28% are skilled labor. The foreigners _may_ be happy to live there but I wouldn't make that assumption without checking. Just because it's better than their alternative doesn't mean it's good, or even acceptable.
