Something similar happening to the ambition-minded?
(Someone once remarked / joked that perhaps America is so stereotypically optimistic is perhaps all the people who left the Old Country for the New World were probably the more adventurous, go-go types, and those that stayed behind were more chill.)
Similarly, we worry about disrupting natural biomes through deforestation or overfishing, but we don't think about sustainability applied to human communities, with a few exceptions (reservations get some attention, though not sufficient attention).
What do we do? For one, I don't think it's hard to make an ethical case for remote first workplaces.
Fwiw, I tried moving away to Seattle, but despite my educational attainment and liberal leanings, I found that I just prefer NC. There's something to be said for living somewhere you don't feel like an outsider. After 5 years in Seattle, I still couldn't lose that feeling.
