Dear All, as asked so much here are some real prices
USA Malaysia in RM approx
Car: eg Ford Fiesta 32-36k 70-85k
Affordable 2 bed apartment NYC vs KL 4,000 2,000
Levi 501 Jeans 90 290
Cheap no brand T shirt 4 10
Beer 0.5 litre in bar 6 25
Chinese food - one rice fish with meat 9-12 7-12
Slice of pizza 3 15
So assuming you rent a room in a 2 bed, have a car (and spread cost over 8 years), buy 10 pairs of jeans and 20 t-shirts a year (to simulate clothing costs) drink 10 beers a week, and for food (7*2=14 meals) have pizza twice and Chinese rest of time (again just for a simple comparison) total annual costs are:
For a couple I assume you wouldn't get a car as good (and cheap) public transport but this is a rough and ready comparison. If a couple take a 2 bed place and have two car in KL (essential) and assume one car in NYC = public transport costs then:
Total monthly cost of living for above items
NYC vs KL Single 5.3k 4.6k
Couple 6.2k 7.2k
The main (only!) thing cheaper in KL is rent and these are rising fast. I know this is rough and ready but I did this as some people (met one recently) believed the "lies" given by cheap skate Malaysian employers who say "so cheap here to live so we pay less"
