Nothing just like there was nothing wrong with kids when you were one but the older generation thought there was because you lived your childhood differently to them.
Kids these days are a lot smarter than anyone gives them credit for. If older people did not judge them based on how much they spend on electronics or how much they sleep and actually took the time to listen to them and ask about their views on different topics, they'd see how much the world would be such a better place if they weren't put down so much during those developing years.
Okay, I'm going to answer this as a "kid", because the rest of you " kids" are clearly to full of yourselves to admit there's anything wrong with us. What's wrong with us is that we are entitled. And just like someone said up there, we're smart. We know how to manipulate. The problem with kids now is their pathetic parents who didn't spank the hell out of us. I was spanked luckily. And guess what? When our parents were kids, they listed to adults. Adults didn't listen to kids, so shut up, because you're not nearly as important as you believe yourself to be, you idiot.
