很好的背景：BA out of princeton, about finishing up a two-year rotation in a top MC firm, and was extended an offer to stay for an additional year.
She had other options as well: an offer from a PE firm, and another one from a hedge fund (no idea about the salary, should be competitive) . She turned down both offers to go to Africa for two years with a non-profit which pays ~20K a year.
The teaching job and the pay in China will attract people who 1. like the job; 2. like teaching in China or. 3. like young ladies in China. This is called self-selection
