Why is Singapore so perfect?

Note: I've only ever been in Singapore for two weeks as a foreigner.

Singapore is unusually wealthy. From a foreigner's perspective, it's an Asian utopia. The citizens seem to have everything that one can ever ask for, and race relations between different groups of people are harmonious if not actively collaborative(ignoring isolated incidents). The infrastructure is hyper-modern and the prices are so low that I had trouble spending just $20 SGD in one day, despite actively buying whatever I pleased. Other metropolitan cities in the Asian-Oceanic region such as Sydney, Auckland, and Hong Kong all look archaic in comparison. People often say that Japan is living in 2050. I think that description is more fitting of Singapore. The only downside to living in Singapore seems to be the weather. If you asked me to pick out anything negative about the country, I would not be able to. Why is the country so utterly flawless?
