They are being exploited. I've traveled to Cebu City where many of these call centers are located. My wife is from the area. To Filipinos, it's a good job, but the quality of life for these workers is still very poor. It's not a living wage; most can't afford to live on their own.
It's a good job but they can't live on it? I think you mean they can't live like westerners.
"most can't afford to live on their own"
That's true for a lot of workers in many USA cities as well.
