There is plenty of Alaska for plenty of people.
The problem is that the people believing Alaska is the holy land have to be very self supporting, only the strong survive, weaklings falter and fail.
I see it every year, big city folk come up here and are totally lost, they cannot even survive in big city Anchorage after 6 months of real winter.
I grew up in Northern Maine. Ditto what you said. Fools from Boston move there all the time to "get back to nature", or somesuch. Those that can stay, do. Those that can't, leave quickly. :-)
I also have a cousin who relocate to Maine from Alaska. She loves Maine, because the climate is "So Much Better". 'Tis all in your point of view, I guess.
I relocated to the Southeast. Life is much easier, if for no other reason than I don't need to shovel my driveway and drive on icy roads just to get to my ridiculously underpaying job for 6 months or so every year.
There are other problems to deal with - with the larger population comes all of its attendant issues like crime, liberals, and the like - but, man, it's just easier to make a living down here.
I wish our weather would scare them off but it doesn’t seem to.
