You have to balance what you're doing now with where you want your career to go, whether you like where you are now (work, location, etc.), and how much you're getting paid. If you're getting paid a lot to occupy a niche that's a career dead-end, and probably won't carry you through retirement, you should leave, even if it means taking a pay-cut. If you're terribly unhappy with what you're doing there or your company or team, you should look for something better. If you hate the area you live in, you should look for a way to move someplace you like better. But if you like where you live, you like the company and the work, and you don't see it as a resume-killer and don't see a problem getting a similar job if something goes south with this one, you might as well stay.
