Not to get personal, but how much money difference are you talking about? $80,000 vs. $200K? $100K vs $150K? $400K vs $800K?
I am in a similar position. I have another 1.5 years (out of 15 total) left of my training and when I get out my salary will go from $40K that I make now to $300K+ if I stay where I (and more importantly, my wife) want to live. If I am willing to move to some less desireable places (for my family) then I could start at $800K. If I was willing to move to Dubai, I could start at $1.5M+. That is a lot more money, but for me it is probably more than I can spend or need for retirement savings. What is it worth to have my kids grow up with their grandparents down the street?
You have to decide what your financial goals in life are and how much money you need to support them. If you can make enough to live the lifestyle you want in a place you want then do that. If you cannot, then you have to decide whether it is better for you to reconsider what kind of lifestyle you want to live vs. toughing it out living someplace you don't want to (hopefully temporarily).
I haven't 100% decided yet (it is awfully hard to leave a half million or more bucks a year on the table), but I am leaning towards staying right here in Texas so my kids can grow up as 6th generation Texans. If I were single my answer may very well be different.
If it was the $80K vs $200K I would definitely have to reconsider though. $400K vs $800K is a lot more money difference, but I think I can do everything I want on $400K.
