I have seen it change a lot. When I first came here, the "Old Guard" continually asked me, "You ain't from 'round here. Are ya."
When I explained that I was from Southern Indiana and NOT New York, I got slowly accepted. Just about 1 out of every 4 cars had a bumper sticker that read; "We don't car HOW you did it in New York!"
Now that the banks have been shuffling in and out people over the years, Charlotte has grown into a more tolerant city. (Yes, the old guard is still fighting the War of Northern Aggression. AKA the Civil War.) Charlotte is a mix of VERY old money and New money. You have families who have ties since before the Civil War and then you have the new money in the form of NASCAR, PANTHERS, BOBCATS/HORNETS. (Just like the East side of Lake Norman is different from the West side of Lake Norman.)
Believe it or not, traffic has even gotten better since 1985 too. (Though it's beyond me why the city planners only plan for the now and not the future!)
In another 30 years, Charlotte may even move into the 21st Century!
The best thing to happen to Charlotte, was when it elected Harvey Gantt mayor many years ago.
