Agreed Neville, but the vast majority of Emirates employees don't live in the Silicon Oasis. Don't forget that although housing may be provided in many packages, the actual costs of providing that in Dubai is significantly different to what it might be in Australia - particularly when the corporation itself is tied up with other local organisations/government etc. Legoland/infrastructure is built by imported Indian workers (OHS rules? Superannuation?), the services are provided by imported Philippino workers... I'm generalising of course, but these underlying non-professional labour costs keep the overall cost of facilities and services down.
The employee value of the package is entirely different to the company cost of the package.
