I think you can draw those conclusions: if you move here you can expect to double your current salary.
Not covered by the poll is the fact that your living expenses will likely more than double, especially if you have to use a car to get to your job. Your vacation time will be cut in half. Health care expenses may rise. Bottom line is be prepared for some decline in your current standard of living.
At the same time, you have the possibility of lottery-style winnings if your employer becomes the next Facebook. Hmm, perhaps you might be better off buying a real lottery ticket.
