I am 40 years old and my parents split up when I was very young, for my generation the sky rocketing divorce rate is one of the absolute worst things for society in so many ways and effects so many people. But it's nothing in comparison to the Millennials and the start of the internet which effects pretty much everyone that's not Amish today. Now with the latest generation and smart phones combined with the internet I've seen it for a few years now that combination will be the downfall of mankind.
If you don't believe me spend some time on Facebook, any dating site or watch a few episodes of Catfish on mtv. I have been at a bar before and seen all 5 people sitting at it on their phones, I remember Christmas a few years back watching a movie with my family and everyone of them were on their phones, even my 4 year old nephew! Once you start to get a feel for the psychology of the internet you start to see that it's a black hole that sucks up everything in it's path. If I didn't need my cell phone for work I wouldn't have one short of for emergencies.
One clear line between my generation and the previous is music and it's amazing where I'm from just how much the music played in bars determines who frequents those establishments. But this happens with EVERY generation and if you don't believe me watch the movie Footloose. To blame music for societal issues or forum issues is laughable, movies play a much bigger role in shaping society but that's not even a drop in the bucket compared to the internet combined with smart phones.
