This thread is about the decline of western culture of which the pop singers, weapons and drugs that you mention are the result but not the cause; which is rooted in the 19th century but came to fruition in the 20th with the shift in the balance of power from Europe to the USA following WW1. Like many people, you attach too much importance to the aforementioned results, which are the most obvious sings of the decline, because a spurious glamour has been attached to them by certain sections of the media. Being a naughty boy is so much more exciting than being otherwise. However, setting aside such considerations, I doubt that my "limited experience" is any more limited than your own in respect of the original post.
