Good Sir Corvus, I feel where your coming from. I myself have gone to many raves over the years, I love to dance and have a good time, and have been known to imbibe alcohol on occasion. I personally believe drug use isn't any higher in this culture then any other, it is just sadly more accepted and not hidden. As far as Goth and "dark side" culture, I grew up around the Punk rock and Goth/Industrial scene, There were many depressed kids in that scene, but in my mind not much more than in the Jock or preppie etc. scenes. Selfishness and the "ME" attitude are certainly very prevalent in Youth today, but that is the same thing my parents said about my generation, and theirs about theirs. As far as Music is concerned their are some phenomenal bands out there right now, in country, folk, metal, rock, and electronic venues. I think the Kid you talked to was depressed, just as many teens are , form all generations.
On that note, I agree, the Selfish "me" attitude is too prevalent, in all generations. The younger generation does learn form their elders, and their elders really are not much better at being selfless. That is why Chivalry is needed now more than ever. I see and have met good honest forthright people from all walks of life and all cultures, I am proud of how positive some young people are, and sadness comes over me when I see a young person without hope, they have no idea how much potential they have. I will get off my soapbox now and let this be.
