I don't entirely disagree, but the first thing that this article brought to mind is the old cliche "wherever you go, there you are". I'm 34, lots of ex girlfriends and lots of past cities. There's a fine line between breaking out of the status quo hamster wheel and running away from your baggage. Moving cities, or relationships, or jobs isn't worth as much if you aren't simultaneously working on yourself
"People travel to change themselves, but they only manage to change the scenery." (Not my quote, alas, and my memory has butchered it enough that I can't find the original.)
And new sceneries have different people, climate etc. also literally changing people (microbiome for example).
So yes, some people travel to run away from problems they never dare to solve, but some people just like to be on the move, like our nomadic ancestors.
