We can all agree that the neighborhood suffers from too much of a good thing - it is one of the few places in the state of Pennsylvania popular with young educated people. The weakness of Roxborough / Manayunk - and NOT East Falls - is that it does a poor job of making these kids feel that it is an appropriate neighborhood for them to put down roots. As you intimated, it is not too late to ameliorate this situation. An aspirational school(s), better quality housing, and, most importantly, marketing / perception control would all be parts of the solution. I have said for a long time that Roxborough being between Gladwyne and Chestnut Hill and being a part of BOTH valleys should be the best of the three towns, but it has been cursed with low-quality development for 70 years, unlike CH and Gladwyne.
