Oh, please. You do know we have adequate rail, bus and car service to NYC? I mean, Martha Stewart often commutes from the Hamptons by limo and her own convertible! A ride from Greenwich, CT is under an hour. Some very important people commute on a daily basis.
I assume people like the Trumps have lavish apartments in NYC as well as secondary homes in NJ or CT or Westchester. Actually, like Bloomberg, they probably fly to their secondary homes.
I’m from Connecticut originally, and you couldn’t pay me to live in NYC (Well, you could, but it would have to be a lot, and quite temporary.)
Metro North and Amtrak were fine for Manhattan, and the car over the Triboro bridge for Brooklyn/Queens, and the Hutcbinaon River Parkway for the Bronx. But some people just need that Manhattan address.
