Can we stop the brain-drain?

The majority of people that I know who live in downtown Philadelphia love it. Yet, if they are young, they presume that it's just a matter of time before concerns about school options will drive them out into the suburbs. The city is finally facing up to this problem and working to keep these prime workers (in age and education) in the city by improving both the school system and the marketing of it. This seems like a good start; if we can keep in the system the families who are most likely to be motivated to work with the schools and force improvements, everybody wins.
