Any figures to back that up? It's said that nothing gets stolen in Singapore, until you speak to Singaporeans. Bikes still get stolen for instance. The city seems super clean, but mainly because low paid workers clean the city really often. If a Singaporean visits another country you'll notice that they're used to the city being cleaned often, not so much that they're behaving differently.
Your "Hawker Centers" have people in their 70s bent forward cleaning up tables to some earn money. Those centers are cheap, but why does the benevolent government not care for those people?
Further, Singapore is pretty much a city, nothing more. Being isolated from any other country helps a lot too.
I think you too easily dismiss the "dark sides".

This is the same as a lot of other countries.
IMO the biggest benefit of Singapore is being a small city on pretty much an island.
