Read "Stolen Fucus" by Johann Hari, at least the first few chapters. A big part of the problem is that there is a while economy around capturing your attention and keeping it: the famous engagement metric. The book argues, rightfully so I believe, that we get way more information than we used to, but in a way that is so fragmented, that we are losing our ability to sustain a train of thought. That is what books had that today's medium rarely have. I don't think it needs to be whole books, but even reading assays of a few page kind would be a move back in the right direction and perhaps teach people the lost art of argumentation, instead of just throwing insults at each other in an eerily idiocracy-like fashion.
