Youth these days - were we different?

My Grandparents used to say it, some of the Senior Drivers on the railway used to say it “eeeh you youngsters, your not a patch on my generation” now without being unkind I am saying it. I flew back from Portugal yesterday (yes my arms are tired😁) and the BA Crew were all early 20s, nice enough but absolutely no personality, I know I was different. Help! When I was young and up to mischief if I was told off by an older person it really made me think, I never would dream of answering back, but a few weeks ago my wife was waiting for a car parking space for 10 mins, a car pulled out and like a flash a young girl nipped in. My wife said “excuse me, I have been waiting” to be told “some of us work for a living” holding out the face of her hand saying “talk to that” I would not have dared. So is it me? Am I being over critical? Any thoughts please.
