This is a big one. I don't live in the Portland area, but anytime I've considered moving any large distance away from where I am I've always rejected it because my family/friends are all in this area. As much as I might like it a lot somewhere else, I'm not willing to uproot my social ties for it.
As I see it the alternative is to stay and advocate to make things better, and while that's grueling I think it's worth it.
I’ve uprooted for greener pastures twice in my life, and it has paid off both times. If I didn’t, I’d be impoverished and possibly hooked on (the scary) drugs.
If fluffy social aspects outweigh your immediate economic concerns, it stands that you are privileged enough to make the choice to stay still.
On the other hand, uprooting requires a certain resilience and fortitude that not everyone has. People who can torch their old life to chase something better are privileged in a way too, are they not?
All that to say I think you have the privilege statement backwards.
