That's an all too common barrier to escape these days, but a person's motivation level has a lot to do with it too. If you perceive the threat is great enough, you'll find a way to move to safety.
As an example; during the Great Depression, both of my grandfathers loaded their wives and kids into their jalopies and headed to California to find work. They were men of almost no means at the time, but conditions were so dire in the Deep South, that they were motivated to overcome barriers you and I would consider insurmountable, to get their families out of there.
When my wife and I decided to uproot ourselves from California, we were sufficiently motivated to figure out a way to do it on just the money that was coming in from paychecks. I look back and still can't believe we pulled it off, but we wanted out that badly.
My greatest barrier at the present time is taking care of my mother, who has multiple health issues, and three different medical specialists. She is receiving what appears to be very good care where we are, and I fear losing that in a move to a more sane state. Getting good medical care established, especially given the current state of things (Obozocare) is a dire concern.
