All this said, I do know several people who work in Irvine, and live in San Marco’s and Carlsbad area’s
(it’s about an hour commute most days).
You can (well you used to be able to anyway) get a much nicer housing situation in the far northern hinterlands of SD than you could in Irvine for the same money.
Some people are willing to drive (especially if work at home at least part time is possible).
