If you grew up somewhere cheap, you probably encountered the attitude that people moving to big cities and expensive states were insane because of the housing prices (and/or taxes and general living expenses). Actual concern over the wellbeing of friends and relatives who did so. For a large segment of people living cheap places, moving to California (as in, the whole state) New York (ditto, except
maybe the extremely rural and also not-popular-for-vacations bits), several entire New England states, most big cities unless you're actually living
way outside them, et c., was seen as simply
impossible. Not in the cards. Cannot be done without ruining your finances. You don't buy somewhere expensive until you retire, and then it's probably in Florida or the Carolinas. On a local lake if you're not rich enough for those.
From that perspective, nothing's changed except that some people living in those expensive places are starting to realize the same thing, and the people experiencing that are a bit higher up the economic ladder than before. Welcome to the lower classes, folks. Don't worry, you've got plenty of company.
