I'm a millennial. First I heard of this term was during a church service. A pastor asked millennials to stand up. He then said we were the generation that would save the world. Apparently we were responsible, ethical, morally righteous than even previous generations. We'd be tasked with "saving" the world. I thought he was a nutbag. I'm not so sure anymore.
I do agree the emerging generation seem somewhat oblivious to moral duties. Right from wrong blurred by Hollywood violence, sex, more violence. Hard to get through to them.
