Sam Ting Wong ,
For sure you are missing something...
Not all pilots in Europe and in America have the chance to work for a major airline.
Some of them are working for low cost , regional , small local companies or are even unemployed.
Some pilot working for regional companies earn in one year what a pilot in EK earn in less than 2 months.
This is only talking about wages but at EK they also get housing allowances or accomodation is provided , they receive school allowances for up to 3 children , medical insurance for them and all their family etc...
So maybe now it will make sense.
