I would say because neighborhoods are always changing and what people really want is what they "remember" about what they liked about a neighborhood. And for old people memory is kind. I live in California where almost by definition everyone came here from somewhere else. In a very nice neighborhood I lived a former strip mall was getting developed. Keep in mind, it wasn't that nice when it was created in the '40 and '50s --hence strip malls-- but now it is nose bleed expensive. What did these neighbors want? Not housing, god forbid they build multiple unit housing! But a Whole Foods or a Trader Joe's would be nice. Yes the traffic was getting worse and density was increasing. Things were changing. But did these people want there houses to be worth 1/5th of what they were worth twenty years ago? Did they want to get paid what they got paid in those days? No, they just didn't want new neighbors.
