At what age do people typically start to believe that society is on the decline?

It seems like the complaints of our society’s decline are age-related. I hear complaints about the weather, manners, youth, culture – usually, the people who make these complaints are quite a bit older than I am.

I am not saying all people over, say, fifty, are prone to whining. Young people complain, too, but I think they often have other topics. They seem to complain about their families a lot, as well as their partners and their money problems. This may just be my impression. I’m interested in yours: What do people your age complain about? Do you hear young people bemoaning the loss of manners or respect for the elderly? Do you think you, yourself, have started to think that things used to be better, “back in the day”?
