>Until they've tried that
Sure. But are you going to pay for their relocation package, plus unemployment benefits until they find a job at their destination?
No?
Oh, then perhaps let's stop suggesting that moving cross-country is easy or cheap for people already living month-to-month at best.
And that's without taking into account that some of them:
1. Have family in the area that they can't just give up;
2. Have their social support network in the area that they can't just give up;
3. Might be a part of someone else's support network that they can't just abandon;
4. Grew up in the area and thus will be forcibly displaced by your suggestion.
I know two people living off a van / RV in the Bay Area.
Both are Bay Area natives. One can afford to rent an apartment, but his work as a bus driver makes the morning commute three hours long. He lives in an RV close to work on weekdays.
Another was renting until recently, but doesn't make enough money as a musician / audio technician. So he's effectively on a permanent tour.
Both are in their 40's and have children.
I guess you can say that they are "addicted" to their families, to their hometown and community, and to their jobs.
Or you can say that they live here, and stop giving infeasible suggestions like "Move to Midwest".
