I whole-heartedly agree. But I also have to say that I met some great people in Dallas as well, some I would love to be neighbors with.
I think the gist of it is, there is always snobby people anywhere and everywhere if you look for them, if you are overly sensitive or if you have some self-esteem issues.
My wife and I were in the market for a new home, when we showed up to an open house, I was in a t-shirt, basketball shorts and sneakers with cowlicks, my wife was in sweatpants. Yes, the seller's real estate agent did take a quick up and down scan at us, but did it bother us? No, because we are confident of ourselves and we have self-esteem.
It appears that the OP started this thread to vent, perhaps he had a bad experience with one snobby person, but then it quickly turned into if you own anything that is more than the bare minimum then you are a shallow and snobby person and that you only brought it to show off or to brag. I mean, these folks think a little too highly of themselves, what is so special about them that other people need to impress them?
All of this is just silly talk and unnecessary burden to be carrying.
