All fair points, but remote work also has increased massively ( http://fortune.com/2015/02/12/lessons-learned-from-3-compani... ). It is interesting to consider that well-paid remote workers, free to live where they choose, may also be choosing to live in these bigger cities. I'm fully remote and I live in a city, albeit a relative small one (SLC), when I could easily pay a ~$300/mo mortgage for a small rural house in the middle of nowhere if I chose to. I suspect that re-centralization is orthogonal to, rather than antithetical to, remote work.
