A very good point - it would seem that Noe Valley exists for families with pre-school aged families that eventually move south to better schools. In my hometown of Pittsburgh, the city has enough housing for 700K people (currently 300K) and the county has like 2M+. Pittsburgh is where people go to have fun in many great, vibrant neighborhoods, but the school system is abysmal, so young, professional families have no interest in living there without being able to afford the private schools.
