In Indonesia many things are actually much more expensive than here: sugar, rice, cooking oil, eggs, meat, juices, fuel, toll, electricity, water, medical, etc2. Eat at mall also more expensive. Cheaper stuff are cleaning agents like soap & shampoo, some fast moving car parts, labor just to name a few.
For Malaysia, free or almost free education you have already right with the public schools? Good hospital, I'd say ok also. Public transport in KL is pretty good actually, way2 much better than Jakarta. Safety, now that has lots of room for improvement here. Affordable house, this is also difficult, other big cities of the world also face the same issue. The key is how to improve average income level so that housing becomes 'more affordable'.
