Three of the twenty wealthiest counties are in New Jersey.  My wife and I used to live in one of them, and, to top it off, in one of the wealthiest towns in that county.  We used to take the Metroliner to and from D.C., observing the depressing conditions along much of the way.

Since my wife is from rural western Penn., and since I'm from a working-class neighborhood in St. Louis, we always felt like misfits on the East Coast.  When we later moved to Arizona, our quality of life improved markedly in spite of our income declining markedly.

The hoity-toities who live in these richest counties see themselves as enlightened, cultured, sophisticated, and avant-garde.  They actually do despise working-class values and look down on the hoi-polloi in flyover country.
