I feel really pity on your answer that good salary can save the fuel of operations. As I said earlier these are the attitude why airlines in India prefer expats as pilots....
My comment was not meant as a joke, there have been several studies by airlines in the US and the EU, AIATA, NASA, that have reached the conclusion that operators of the same type of A/C but different overall levels of satisfaction with their conditions of employment, showed a significant difference on the efficiency of the operation and that translated into different overall fuel consumption per seat/mile, sorry of their conclusions ruffled your feathers.
