Yes I agree with that, and additional to the lower costs it also funds a local economy for the residents of Dubai.
The problem is that QF keep telling everyone that their labour costs are too high and look at Emirates and how cheap their labour costs are. The problem is that it is not a fair comparison and realistically one that cannot be made as the government and EK are working together for the betterment of Dubai. In Australia QF are being hamstrung by everybody and everything. Hence the high cost of doing business in OZ.
