People considering jobs at CX should have all the info. The pollution (while in no way CXs fault) is a strong factor in whether or not you will be happy here. If you have the choice between Hong Kong and elsewhere you might choose a cleaner enviroment for your family.
Believe or not some people do put their family's needs and health ahead of money. Not that Cathay is the top of the heap by any means these days.
