This leaving idea is part of human behavior - when one is in a terrible situation, one thinks another place has to be better, so the person leaves A and goes to B. In a regional emergency, that would be true but if the whole country is down, likely place B is no better than A and the person isn't familiar with B which puts them at a disadvantage when they get to B.
I have made my own country in which to live and it's my house and small back garden. I am the President for Life of my country and if half white Hussein brings this country down, I'll stay in my country until times get better. I am prepared to do that starting today if it was necessary.
Good point.
Where ever you go, where ever you decide to live, build the culture you want to live in. Build the country you want to live in.
