Fair that you can look to reclaim use of buildings during non-school hours. Though, that almost certainly gives rise to more need of parking, such that I'm not clear on where that would go for this discussion. :D Indeed, local schools to me are used by some church groups on weekends. Such that the parking lot is filled on weekends for that. (And churches, themselves, are often mixed use for preschools and such.) I think the efforts to lower costs by being creative is worthwhile. I am personally skeptical of many initial ideas, but that is no reason not to explore them. And you are right that many of these things almost certainly interplay with each other. But, the more expensive the housing and general land use is in an area, the harder all of these tradeoffs will become. Regarding the service jobs, many older service jobs were traveling services. You can't go to a roofer's to get your roof fixed. Nor did you historically go to the doctor's office. Since delivery vehicles were rather costly and large, it wasn't uncommon for most people to not go and buy things on the regular. Certainly you didn't load up the equivalent of a car's worth of groceries to bring home. Indeed, the milkman was a job. None of those services would have had you living where you work, as it were. And labor jobs, which were also very common, were definitely not performed at home. So, again, I'd be interested in the numbers.
