Nannies in Singapore

My boss is pregnant and due at the end of May.  This week will be her last week at work, and then I will be on my own!  She was telling me about live-in-nannies in Singapore because she has hired one (I think she lives alone.)  The nanny will work 6 days a week, 24 hours a day, with Sunday off.  She will cook, clean, and help take care of the baby.  She costs S$700/month!!  Which is about S$595 after taxes!  The nanny is from the Phillipines and her 3 kids are still in the Phillipines.  That $595 that she makes will put her 3 kids through college back in the Phillipines.  Wow!
