I wouldn't have moved to the Bay Area if there weren't as many jobs as there are. If you have the choice to relocate, you might as well go where the jobs are, right?
In today's economy it's usually easier to find a new job in a high CoL area.
Not in San Diego! High CoL area, relatively low wages, and tech jobs are relatively scarce. We moved to the Greater Salt Lake City area three months ago because CoL is much lower here, and there's a plethora of opportunity.
