Academics — who tend to move around all the time – have great difficulty understanding in their informal writing and in their official monographs why poor people don’t just up and move when economic conditions decline in an area.
If you’re already destitute and don’t have a job lined up already, traipsing to another faraway city where you have no social connections and nothing to fall back on is just a terrible idea. It makes no sense at all.
Also, I shouldn’t have to mention but I will the fact that most people actually want to live near their families and friends and not abandon them every two years when the neolib overlords decide to blow up the world again.
