His way of living in Singapore is not what I can afford!
Well, that's the biggest problem with Singapore - and Hong Kong. Very capitalist places, but achieving anything close to the typical suburban American quality of life costs millions.

Of course, Americans are probably on the verge of losing that quality of life, too.
