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?
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.
It cuts both ways.
