There are a lot of valid concerns with regards to Singapore's excessive central planning, governmental and social disapproval of nonconformity, etc. But this piece really does sound like the perspective of a disappointed poverty tourist. There is a huge difference between visiting filth and slums and red-light districts and desperate people struggling to get by, and having to live there all your life.
Singapore did a lot of things wrong, but part of the reason it is so (unnervingly) clean and prosperous and ordered is because the government has made an effort (not completely successful, and again perhaps with not all the right methods) to provide the denizens of the country with places to live and ways to make a decent living.
