Sure, Leonardo DiCaprio, Richard Branson, Albert Gore, Barrack Obama and high schoolers are impressed, but not the mom and dad working jobs that are teetering, driving beaters and facing pressure from cheap labor. They see these people jet-setting being hyper-overconsumers and think, what the hell? They see these people increasing their wealth promoting change, but they don't change. Why should I change, they're not changing, they're adding more!
