All of Scotland, and especially Glasgow, has changed A LOT since your wife was growing up. Even in the 13.5 years I've been here things have improved. My husband grew up in Edinburgh, left for 18 years, then we moved back 2 years ago, and for him it's a completely different city. I don't think it's stuck up at all, or at least it depends where you are. Some neighbourhoods are posh and some are normal and some are shite, like anywhere. I love living on in Edinburgh, and I hate Glasgow, while others are the opposite, and some like both, but basing your opinion of the places based on experiences more than 10 years old will not give you a realistic view of it is now.
