Please take note that I said so many, not all, as there are still some great kids out there. But... rudeness, backtalk, entitlement, foul language, drugs, suicide, bullying are all out there, too, and in far, far greater numbers than my youth. Sad.
I hear the anger and the rudeness and some of the advice in some of these responses from, I assume, parents, and even those who claim to be an expert in child mentality, and think no wonder.
It must be difficult raising children in today's world. There's so much to have, and they either have it all or, the other side of the coin, have little of it. Some kids are told no, often with a backhand, and others are never told no. It keeps them quiet and out of parents hair rather than having to deal with them, and they don't have, or don't want to take, the time to deal with it.
Those famous last words, in my day, many families had 5, 6, 8, kids and they all usually grew up to be reasonably decent and caring young adults with commonsense and empathy and decent values. These days, so many families have one or two, and they can't handle it. Oh, they think they are, but when you see the finished product a few years later when sometimes it's your kid that's the bully or on drugs, maybe they didn't do so hot.
Just my opinion and observations, but, you asked, I answered.
