It's exploitation, even if all sides have some benefits.
I think some here are reasoning too much from their western perspective, and this isn't the kind of thing you really tend to see if you just visit for a week. Is it exploitation? Sure, I never said it's not. Everyone should deserve a reasonable minimum living standard, and it's sad I see so many people who don't. Yet at the same time, a lot of Indonesians still see as a "good deal" for them, exploitive or not, as it's just a better life than staying in Indonesia. This doesn't make it right, but it does explain it. There's a reason this women went back to Singapore after her negative experience.
In many ways, this is just as much of a failing of Indonesia's government who fail to solve basic problems as they're too busy siphoning money to their own accounts or getting lost in petty religious/ethnic arguments.
