I think it's a love hate relationship. Because NJ is not NYC. Because we can laugh at NJ. Because it stinks and the roads don't line up.

When you're young and broke, you live in NJ and claim NYers are pretencious. But you come into the city & party all night and all weekends. Then the second you can afford Manhattan apartment, you sell your car & move back and laugh back at NJers. Gradually, you have kids or you bought too many pairs of shoes, and you make more money, you get sick of living in a small cage, and what else can you do? You move back to NJ (because Brooklyn is now as expensive). And in couple more years, your kids grow up, you get tired of people laughing at you living in Jersey, you move to Arizona or Texas.
