You must be coming from a country with National Healthcare or another Asian country. If you are from the US however, medical care here is cheap!
Basic necessities in the US are not necessarily necessities here. A car being a very non-essential need in Singapore. The entire island is criss-crossed with airconned bus services that are in good shape and run on time and a decent frequency. Additionally, add in the MRT and the multitudes of taxies that are STILL a whole lot cheaper than in the US or other western cities, there is no 'real' necessity like there would be in a western country were the buses stop at the city limits and the same with rail services. I sold my cars here some 18 years ago and don't regret it at all. I have to have my car at home though as I live some 30 km from the nearest town. You don't have that problem here.
Decent accommodation can be had here for decent prices if you get rid of the swimming pools & gyms that most don't use anyway. From what I see back home in the major cities, the rents are not that much skewed for a major metropolitian city like New York. Actually, you will find the prices are much the same if comparing the two. Big difference is there is no real daily gridlock on the roads here like in NYC.
