Why to hit on the earning individuals?? its the company who has a policy to pay on what they feel fair scale. if a company feels and favours brit/american's for a post, so be it. whats the big deal. and why to compare the salary at first place, if you are satisfied with your pay you stay if not you have every freedom to go back to your home country. so lets be happy on what we get and give our fullest ethically.
these comparison would only bring downfall and dejection.

life is short and highly unreliable,live to the fullest... :-)
