I don't think remote work would result in bringing us together at all, quite the opposite actually. Frankly, the existing populations in the states people have been leaving for decades are very culturally different than your average remote worker. The local population will see this as cultural colonialism by coastal elites, and the remote workers will wonder why they aren't welcomed, all while driving up local house prices/rents, overtaxing the already crumbling infrastructure, and causing those places to lose their "local charm".

Not saying I agree with either perspective, but I think it's very naive to assume WFH could unite the increasingly polarized american peoples.
