Jinchafa,
My only thought on this is why western teachers think they should be paid so much more than the local teachers. And I'm talking only wages here, not the other perks that locals only dream of.

I didn't get into teaching to become rich -- obviously, and I certainly don't mind making as much money as possible, but I often wondered why I earned so much more than the local teachers for doing the same job. I'm not complaining, just curious.
