Australopethicus,
Mate, no one is earning 320k flying for a Chinese airline. CSA are paying more than the old CA rates but not 320k.
But the point still stands; the wages bill in the cockpit of a Chinese airliner is very low compared to the west despite them carrying 1-2 more crewmembers per sector. Expat salaries even using your inflated figure still represent a very small sample of crewing costs.
You will notice we are not arguing on the same page. I made reference to COST to the airline; your approach is INCOME to the pilot.
Very different things from a personal perspective yet one is much more important than the other.
