How rich are Singaporeans?

A recent survey claimed that Singaporeans are the 4th richest in the world with net worth of US$336k each or something like that. So how to compare this money with someone with only $30k to see who is richer materially? Of course the Singaporeans have more money, big and strong Singapore currency. The deception is only beginning.

Think of how hard it is to save $100k and how fast it slips
