They're not going to be unemployed, they're going to find a better job. In my mostly-uninformed opinion I think that remote work has allowed a lot of people to search for work in other locations and this has radically changed the way the employer-employee economy works. In smaller job markets talented workers didn't have much choice about where to work and there were factors to changing jobs (like commute distance) that made them rule out a lot of places.

Now, there's an abundance of positions available remotely all over the country and you can shop around for a good fit.
