Tri I am fairly confident when I say that BA, DL and LH pay their pilots way more than EK pays its pilots. That is not to say that those pilots make more than Emirates pilots (that argument is for another day) just that those companies pay more per pilot than Emirates as a company does. After all what is EK labour cost? Way below 20% probably near 15% and the other airlines are mid 30%.
The medical costs are picked up for the most part by the airlines and those pilots enjoy fabulous health care with some really good doctors.
The pilots have to pay for their own housing as I'm sure you know in your cheeky question but it is quite reasonable to live in N America and Europe somewhat. Much more reasonable than Dubai and your money goes a lot further there than in the Middle East.
You are not really comparing the big legacy carriers to the Middle East carriers are you? I don't think there is any comparison.
