Apparently the issues experienced as a result of high housing prices aren't valued enough to drive prices of the homes down, yet.
I guess my point, if I had one at all, is that it seems like the housing market is absurdly high in such a way that will eventually self balance, one way or another. Either the city will continue to sustain itself on the backs of the long commuters who can't afford to live in the city, or the quality of life in the city will drop, which will in turn lower housing prices until the workers who make the city life appealing can afford to live close enough to again commute reasonably.
If, as you say, education is suffering, people will stop buying the houses, or they'll stop bringing kids to the districts. Either way, problem self-corrects, right?
