I am a millennial, and I've read a lot of blogs and editorials, from in and outside of the Church, that either encourage or depress readers (but never a combination thereof).
But this isn't an article so much about millennials as it is about social (and pending economic) change. And it's a bit spooky, to say the least. Socio-cultural change like this can't come from one factor alone (e.g. technology/social media).
