You're exactly right, theglidd. Our zip isn't a super zip, but it is very close at a 94 (highest in our state, though). I looked at the average net worth linked above, and my area has an average net worth of $501,000. So, obviously, not everyone in the area is living beyond their means. I'm also proud to say that we, just this year, became average for our area!!! (Never really aspired to be average, but in a nearly-super-zip, I'll take average!)
I like my nearly-super-zip because the schools are great, crime is low, lots of professionals w/college educations. It helps that we chose the reasonable neighborhood (purchased our 2300sf 4br3ba for $230,000 as opposed to the houses across the street that are 3000+sf for $450k++++). We are living well within our means and don't let the spendthrift community influence our activities or purchases.
