Certainly, I'm specifically talking about the highly-paid knowledge workers in cities. But if they move out to any large degree that cascades. You don't need the higher-end luncheon spots and other amenities those workers use at that point. There aren't generally factories or distribution centers in cities.

It may even be a positive for some of those workers to the degree prices go down, albeit with fewer high-end restaurants and so forth and fewer co-workers.
