Your salary is a negotiation. Your company wants to pay each employee as little as possible. If you are unhappy with your salary you should look somewhere else. In fact, that is why companies pay people in expensive areas more. Those expensive areas have more available jobs so employees are more likely to leave. If you want those employees to stay you need to pay them more than employees who have a harder time leaving.
