Music is a wonderful thing, but it can also be used as a weapon. Over the years, each generation has recoiled upon listening to their kid's popular music.
In the late 40's and 50's, the rock and roll revolution started a rebellious trend among young people that some blamed for the problems of the day. The psychedelic music of the 60's started a rebellious trend among young people that some blamed for the problems of the day.
The punk rock music of the late 70's, the metal years during the 80's, rap music in the 80's and 90's, and whatever the garbage is that they have now, when a style of music would catch on, it was always exploited by the music industry and then the music world becomes flooded with garbage that gains more popularity than the musicians that defined those categories.
Every single generation is shocked by the music their kids listen to. Go back and listen to some of the popular music from your formative years and really think about the themes they push. Rebellion, partying, living to excess, shirking responsibility, rejecting authority...
And it's not just the music... Popular TV shows and even popular films have done the same thing. Think about some of the stuff that has popped up on TV over the years to influence young people to live like there's no tomorrow... Really think about it, I'm sure you can come up with a handful of examples from your generation, right?
These problems don't begin with the songwriters or the bands. These problems begin when the music industry identifies popular trends and exploits them. They bring young, talented bands in and give them big money to record "their" music, when in reality they're gently shaping their careers to make them into something they never were. But, they keep throwing money and whatever they want at them to keep them compliant and making the songs that top record executives know will sell, but end up shaping society into something we don't recognize...
