Within the last 2 decades, it seems clear to me that pop culture has degraded heavily, and in order to view how rapidly Western society has declined in terms of quality of entertainment, you'll need to look no further than hip-hop and rap music. When I was a child (late 80's, early 90's), I remember rap music being something fun, clean, vibrant, and generally speaking with a message behind it. How can we go from listening to our favorite rappers perform about important topics such as racial issues, equality, freedom, and social liberty to 26'' chrome rims, big-assed prostitutes, and selling crack cocaine? A pictorial representation by yours truly, if you will allow me to post an example:
Clearly the differences are undeniable. Now I realize there were some rappers "back in the day" that talked about ass and gold, but at least the English language was involved. I also realize that there are still technical rappers around today that perform about current events, unfortunately you don't hear any of these songs on the radio - our watered-down generation simply does not want to hear them.
If these trends follow suit, what will become of our society in say, 30 years? In 2041 will a performer jump on stage, have public anal sex with a groupie, grunt to the beat, and spit expensive liquor all over the crowd? Is that what we want? Something has to give.
