I've faced this a few times. There were times when I knew that the situation would change and stayed, but I left when I was in your situation and knew that any form of change would be years in the making and my skills would atrophy in the process.

You might do well to learn something while you are there. I was working on a VB6 and mainframe terminal application in the mid 2000's and still managed to extract some value.
