singapore has ALOT of people stowed on to very little space, so they have very, VERY strict rules on littering. you're not allowed to chew gum because... well... if everybody chewed gum, spat it on the streets, the streets would be covered in gum. basically you can get fined heavily for littering in singapore. There's also censorship, restricted freedom of expression, homosexuality is illegal etc. but they have a VERY deregulated economic sector, so nobody cares, right?
