The trick feels like it would be to get pay like your area's, in a place like cost of living like my area's.... (well, trick for helping oneself).
...and that's what remote working is for ... supposedly.
Thing is, it doesn't work like that, does it? A lot of jobs can't be remote all the time. Or even some of the time.
And even if you are lucky enough to have one of those jobs, there is a reason that desirable places are desirable. Temperature, schools, beaches (or mountains/wildlife), proximity to culture ... those sorts of quality of life things.
Still, I think there will be an increasing number of people who take advantage of the lower-cost areas to live. I mean... at some point they have to, right?
(FWIW, this insane housing market has caused a lot of people to finally "cash in." Which means that we are losing a lot of the basic "services" that you need. Teachers, firefighters, police, waiters, retail workers? They need a place to live, too.)
