> I wouldn't be surprised if a sort of rural gentrification occurs in the handful of Midwestern towns that have gigabit fiber. Would those areas remain low COL? Would the existing inhabitants become a sort of underclass?
You'd see something like that, but keep in mind that outside of dense urban cores, you mostly don't have the same constraints on available real estate that drive existing residents out by rising prices (and the SF Bay Area's lack of housing inventory is largely self-inflicted, unlike, say, Manhattan).
So, yes, some competition from well-heeled newcomers will drive prices up a bit (encouraging new construction), but without a constraint on housing inventory that drives the newcomers to compete with each other, what you get is just a bit of urbanization, rather than gentrification per-se.
