This NY Times article made me think. One of the main things that parents are looking for when choosing where to live is the school system. So why aren't more property owners and developers trying to invest more money in the school system both to raise the value of a new development and to raise property values in a less well off neighborhood? Are there legal hurdles? A failure of imagination? Or simply complacency do to the idea that schools are mostly the government's job?
[The article does make clear some developers are investing in NYC but are reliant on public initiative for at least some of the funding. I'd guess that NYC is way ahead of the curve here given insane property values ($2 million for an apartment!!!!) so even less of this is likely elsewhere. Though I don't have the data so could be way off on this assumption.]
