Much of what you are saying is true, BG, but, over half of our kids friends who don’t want to move out of San Diego did receive college degrees, and then decided they didn’t want relocate for jobs.
They can’t get the jobs they want here, and they don’t want to move. Not a pretty picture for them or their parents.
In addition, others who have left for jobs have not been able to get back with comparable jobs, let alone buy homes when they do return.
