Furthermore, if you live in an expensive city, you might only be able to afford a small apartment, to ensure that rent doesn't eat up too much of your salary. In SG, someone else might be perfectly fine staying with his/her parents, thereby saving more $. There are a whole host of factors to consider based on what each person considers a "good" standard of living. And... we haven't even considered other intangible reasons.
