Is Singapore an unpleasant place to life? If so why do so many people want to live there?

I'm open to being corrected on this, since I don't have a good source for Singaporean immigration statistics, but my prior is that people who choose to live in Singapore are coming there from other places that are much more corrupt while also still being rather draconian (China, Malaysia). I'm pretty sure well-educated Westerners could get a well-paying job in Singapore, and the reason few move there is not, in fact, about economics.
