I am a young person, very interested in what's going on the world. Though I agree with the article that a lot of my generation isn't. They are (generally) really focused on themselves and what directly affects them. Which happens to not include world-suffering, war, etc. That's why we are more and more being referred to as the "me generation". We are taught that we are special in preschool to build self-esteem, but there is never an end to that teaching.
Luckily, there is enough young people who care, who really care, and aren't afraid to make a difference, to make this country better. You need not worry too much about the future, but don't ruin what chances we have.
