It's a cliche by now that oldsters always think that youngsters are spoiled by having it too easy. "In my day, we had to walk to school uphill two miles in the snow" etc. And, like so many other cliches, it's true!
Things used to really suck, and now they're a lot better. That happens every generation--mankind's physical culture does keep on improving in a lot of ways. Older people are proud of all the progress they've made. And young people take the new and improved stuff for granted and complain.
But that complaining is a good thing! Expectations keep increasing with every generation. If we didn't always have new people coming on scene and getting frustrated with the status quo, then we'd stagnate as a culture.
The kids are all right. It would be nice if they appreciated what they have more. On the other hand, they'll get old and have the same experience too.
