If you compare specific job for specific job, the pay will almost always be the same. For those who would like to know the truth about the differences in negotiated pay for the same job......watch this video of a recent very famous interview on the subject(where the interviewer with a specific agenda attempts to mis-quote and mislead the interviewee who sets the record straight). While I suggest starting from the beginning, you can get directly to the specifics of this topic at 4:50.
