I don't see the problem. Many Americans choose to live in the suburbs anyway, and inside the city you can't avoid noise one way or another. Many frequent flyers prefer a centrally-located airport instead of having to travel a long way out of town, like IAD or EWR.
While EWR may be away from New York, it is hardly out in the sticks. It is right in the middle of densely populated area which was densely populated before EWR came into existence. And EWR was the first airport built in the New York area and has been in continuous commercial service since it was built.
Both JFK and LGA were also built in areas that were only somewhat less populated than they are now.
Meanwhile New York TCO has changed flight paths all over creation having them suddenly appear over places that are nowhere near the airport with planes flying overhead suddenly as low as 3 to 6k feet. So contrary to the way it is being made out by some, it is not all the fault of the hapless homeowners. How heck is someone in Rumson NJ supposed to know ahead of time that they will suddenly be in the approach path of Newark?
