Singapore is an unusual place. It's isolated, beautiful, clean and safe. There are lots of great places to eat, drink and hangout and being just shy of the equator the place is rather lush with vegetation. It's also a gated community bulging with skyscrapers, ex-pats and clammy weather so attracts a certain well-heeled crowd.
The 15% tax rate fills the place with high-end economic migrants, making it a global centre for trade and shipping, and it is a nice place to live - for those with money that is. For calling the place "expensive" doesn't even begin to cover it. Most things including food and drink seem to be 2 - 3 times even London prices.
And this little paradise island also has some tough rules to accompany its good living. Apart from the well-known no spitting and no chewing gum laws, commiting more serious crimes can prove costly or even fatal. Some have described Singapore as Disneyland with the death penalty. Singapore has the second highest per-capita execution rate in the world. The semi-authoritarian regime is run by a governing party that has been in power since 1959 and their motto is effectively, "If you've done nothing wrong you've got nothing to fear." Now where have I heard that before?
So Singapore is a nice place to live, expensive but nice. Just don't break the law.
