You make good points.
The job probably doesn't mean more then the family but absent a job you can't take care of a family either.
So leaving has to be balanced with that reality. As does moving out to the country. Though the current trend towards working from home has made the latter more obtainable.
Again this isn't about the easily gauged emergencies such as a hurricane. It is about knowing when to leave for the things that can't be known ahead of time.
Though as is the constant mantra over on actual survival forums, "absent a prepared and welcoming destination, bugging out simply makes you a refugee and the bug out bag just makes you a slightly better prepared refugee."
