As with all things in employee/employer relationship it is about leverage.

Why should you get paid less for doing the same amount of work? What does it matter to the employer?

The question is, how much will it cost your employer to replace you? Presumably, they will be hiring your replacement locally so your salary should be compared to local wages.

The trick, is to make yourself indispensable (or at least very, very expensive to do so). Focus on being the sole owner of crucial products and knowledge (we are after all, knowledge workers). If you find yourself in a position where redundancy is being put in place (i.e hiring someone to shadow you, etc. then it's time to move up the knowledge chain or to a different product).
