And thanks to this "tax", Eastern Pa. is being flooded with these people.
Eastern PA is being flooded with former NJ residents because it is impossible to build housing in New Jersey anymore. Unless you are connected to the right people and know who to pay and how much, you are not going to get permits for a residential development. The system is so convoluted, and you have to jump through so many regulatory hoops, it is just not worth it anymore. And at every stage, there is some bureaucrat or politician with his hand out, waiting to be greased.
Hey, it works for me, because I have an existing house that is artificially expensive because housing is so scarce an nobody can build more. But now the town wants to raise my property taxes because I'm obviously such a rich guy because I live in a $600,000 house, never mind that it was only worth $120,000 when I bought it.
Nobody wants to make that ride all the way out to the Pocanos. All that empty space between Parsippany and the Water Gap would have houses on it, if anybody could get the permits. But they can't, because they don't have an in.
