I grew up in what is now a 61, but at the time it was probably higher as there's been an influx of people moving from Memphis and the annexation fever of the previous mayor of Memphis since I left for college. I went to high school in what is now a 78 (was probably higher at the time because it wasn't annexed yet by Memphis) and I was one of those kids who drove a luxury car. I had a '92 Range Rover, then a '93 BMW (this was back in '03, so those cars were over a decade old). Both of them were hand-me-down cars that were paid for. The Range Rover was a gift for getting a 30 on the ACT when I was 16. I went to school with kids who drove Hummers and newer luxury cars.
My dad made over $100k annually from his regular job plus he owned several dozen rental properties. My mother stayed at home and managed the business's finances. When I went to college, they moved into a 6000' McMansion with my 16 y/o sister. I'll definitely admit that I was spoiled, as was my sister. My parents insisted that I go to Vanderbilt rather than the University of TN. VU paid for the majority of my schooling and I feel I got a great education while I was there, so I have no complaints about that. For some of college I lived in the dorms, when I lived off campus I moved into a more affordable 41 ZIP code that was home to a lot of immigrants from various parts of the world (Ethiopia, Somalia, Egypt, Vietnam, Mexico, El Salvador, Bhutan, etc). That ZIP code was a lot more interesting and I could afford to do more on my part-time job's salary and financial aid.
I now live in a 58 ZIP code outside of Atlanta. I've decided that, based on past experience, I'm generally happier in ZIP codes with lower numbers. There are generally fewer pretentious assholes, better and more unique restaurant options on the rare occasion that I go out to eat, and it will allow me to live below my means while maintaining what I consider a high standard of living. I'm glad that despite my upbringing, I've maintained some strongly anti-consumerist ideas. I'm not looking forward to having to work in an 84 ZIP, especially as someone in a service position. But the money is good and no situation is ever perfect. Money aside, the only advantage is probably having more access to free stuff that I can sell via CL.
