What is up with kids anymore?

It seems like so many people these days have divorced parents. I am fortunate enough not to have divorced parents, although we still have our own issues. Dad is handicapped, don't have a lot of money, siblings and I all were "blessed" with some sort of mental disorder, there's drama, etc. But we all respect and love each other. I don't understand how there's so many kids who HATE their parents just because they are divorced though. Maybe I don't understand, but if my parents were divorced when I was younger, I wouldn't hate them and cuss out my stepparents. Don't kids realize they're trying? Maybe parents need to sit down with their children and pay more attention, but I know so many people who just HATE their parents and treat them with zero respect. I know a girl who was the worst, her parents were divorced but her parents also constantly told her they loved her, sent her letters, gave her money, and she demanded these things. She cussed them out and would scream at them. I said just because you come from a broken home doesn't mean you can treat your parents that way..and she just cussed me out, too, and said you know NOTHING. And said I was stupid, etc. It hurts me to see how my generation is growing up like that. They are growing up now being more promiscuous, drinking younger, smoking younger, with more broken homes, but they are disrespecting their family so much. And treating their peers with such disrespect as well. If you're not cool or don't fit in, like me, they kick you to the curb. Also, I'm sure parents are partly to blame. They don't watch their children. They don't instill family values. I also know a handful of people who have divorced parents and they all get along and have turned out okay. and these are the families who have done the right things. I just want some opinions on this matter. I feel like parents have gotten "lazy" but why are kids so disrespectful to their families and stepparents?
